However, the 270 WSM uses a heavier rifle and the .270 Winchester gets a slight edge when both are used in the same weight rifle. These are interesting cases where both lines of ammo use the same style bullet for both cartridges, but the Nosler ammunition uses a heavier bullet for the .338 Win Mag and Winchester uses a heavier bullet for the 325 WSM. None of them have covered any new ground. The 270 Winchester Short Magnum very likely does gain some accuracy benefit from its shorter powder column. The last of these cartridges, the .325 WSM, was introduced in 2005. To get started, click the link below to visit mymagnow.com and learn how to access your digital magazine. All are very solid performers that are extremely popular with big game hunters pursuing game like deer, elk, black bear, and moose. However, standard/long actions and short actions are two of the most common and are most relevant to the development of the Winchester Short Magnum line of cartridges. Just put your shot were it needs to go. Winchester Model 70 chambered in 7mm Remington Magnum & Remington Model 700 chambered in.270 Winchester. In order to make as close to an “apples to apples” comparison of the cartridges as possible, I referenced Winchester’s 2009 catalog and used the provided specifications listed there for the Model 70 Featherweight chambered in .270 Win, 270 WSM, 7mm Rem Mag, 7mm WSM, 300 Win Mag, 300 WSM, 325 WSM, and 338 Win Mag. The 270 WSM is relatively popular itself (probably the second most popular Winchester Short Magnum cartridge behind the 300 WSM), but it can’t hold a candle to the .270 Winchester in terms of overall availability. First, the 7mm Remington Magnum cartridge is significantly longer. Even so, I’d personally lean towards .338 Win Mag since it generally functions more reliably, shoots larger diameter bullets, and is usually a tiny bit more powerful. Scroll down or click the appropriate link below to jump to the specific comparison you want to learn more about. You would think the popularity of the .270 would’ve spawned a ton of competing cartridges that fired .277-inch bullets. Subscriber Services. The .338 AccuBond load has a small, but definite advantage in wind drift at all ranges, but the 325 WSM has a bigger edge over the .338 Win Mag with the Winchester loads. Once again, the 270 WSM has a slight advantage over the .270 Winchester in this area. Rifles and ammo are widely available for both guns, but with an almost 80-year head start you’ll encounter more .270 Win. All four loads used a 200 yard zero.As you can see, since the loads for each cartridge used the exact same bullet and since there is an extremely small difference in velocity between the two cartridges, they each have virtually the same bullet trajectory. The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.As you can see, that particular 325 WSM load has about 83% of the free recoil energy of the .338 Win Mag load, which is a pretty major reduction in recoil. The exact size of the rifle action (which includes the locking bolt, firing pin, etc.) For those reasons, the two cartridges have very similar case capacity, but the 7mm Rem Mag can hold a tiny bit more powder than the 7mm WSM. Both are also capable of outstanding accuracy in the right hands. After all, the .300 Win Mag is capable of excellent accuracy itself and is generally very highly regarded in that area as well. In the WSM .270 fans found a short, powerful, efficient round that could be housed in compact, lightweight short-action rifles and which edged closer to 7mm Rem. The first three cartridges were all designed and marketed specifically as short action alternatives to extremely popular and effective standard length cartridges: the .270 Winchester for the .270 Winchester Short Magnum, the 7mm Remington Magnum for the 7mm Winchester Short Magnum, and the .300 Winchester Magnum for the 300 Winchester Short Magnum. Like I mentioned a minute ago, that particular 325 WSM load above has essentially the same trajectory and still has about 95% of the kinetic energy of that .338 Win Mag load. 7mm WSM vs 7mm Rem Mag OSG's Lynn Burkhead and Ruger's Matt WIlson kick off SHOT Show 2018 by taking a look at the Ruger Predator. Theyâre pretty much the same thing. However, both Nosler and Winchester manufacture their Trophy Grade and Power Max Bonded lines of ammunition in both cartridges. Looking at this Nosler reloading page for the 270 WSM, it shows you can push 150 grain accubond long range bullets with a BC if 625 at 3150 fps. The difference is not, however, extraordinarily dramatic. However, the rifles are noticeably lightweight, offering non belted magnum performance; that all shoot accurately. That’s a pretty major step down in recoil, especially when you take into account that you’re getting almost the same amount of performance out to 200-300 yards. I’d have to compare the ballistics to double check Ballistics Comparison for 270 Sep 12, 2010 #6 2010 Ontario F Class Champion used a 270WSM necked up to 7mm. with advertised prices as low as a dollar a round for quality ammunition. There is a decent selection of factory ammo available in the cartridge from companies like Federal, Hornady, and Winchester. Caliber: Bullet Weight: Overall Cartridge Length: Muzzle Velocity: Trajectory at 300 yds(100yds zero) Muzzle Energy(Ft. Like its siblings, the .270 WSM has gained a steady following for a variety of reasons. The verdict? 270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? The two Hornady loads fired the same bullet with a scant 30 fps of difference between them, with the .300 Win Mag having a tiny velocity edge. If you already have a quality rifle that you like chambered in either cartridge though, I don’t see any compelling reason to make a switch to the other one unless you just want to. Mag. With these loads, the bullet from the 7mm WSM is going 50-60 feet per second faster than the bullet from the 7mm Rem Mag. The recoil of some hard hitting cartridges. Is it significantly more accurate than the .270 Winchester? In terms of trajectory, the newer cartridge has an edge, but it’s relatively minor. scorches past the 6.5 Creedmoor in terms of sheer speed, but in terms of rifle... Give a Gift
Basically, the .270 Winchester and .270 Winchester Short Magnum are best suited for the same hunting situations. Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. Are you just itching to take a rifle chambered in one of these cartridges on a hunt? 300 WSM vs 300 Win Mag This specific model weighs 7.25 pounds when chambered in 270 WSM and 7 pounds when chambered in .270 Winchester. The data used to compare the trajectory and wind drift of the cartridges was obtained from Hornady (here, here, here and here), Federal (here, here, here, here, here, and here), Nosler (here), and Winchester (here). Again, probably not. Both are also very good choices for hunting game like bighorn sheep, mountain goat, Himalayan Tahr and chamois. All four loads used a 200 yard zero.Just like you’d expect, there is virtually no difference between the trajectory of each cartridge. Due to the long running popularity of 7mm cartridges like those just mentioned, there’s a great selection of quality bullets to choose from for both cartridges. Additionally, the Winchester Short Magnum Cartridges all have a case with very minimal taper and a 35 degree shoulder. The Big Game Hunting Blog is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, Amazon.ca, Amazon.com.au, and other Amazon stores worldwide. This is illustrated in the table below comparing Federal Premium factory ammunition loaded with 130gr Trophy Bonded Tip (.44 BC) and 150gr Nosler Partition (.466 BC) bullets in .270 Winchester and 270 WSM. Specifically, the new 270 WSM, 7mm WSM, 300 WSM, and 325 WSM cartridges were all designed to use a very compact case that would fit in a short action rifle. (Interestingly, this seems to matter minimally to buck deer. You can even use them both on larger game like kudu, eland, red stag, elk, and moose with great results. These three products from Horus Vision, a smartphone app, pocket weather meter and laser... Thompson/Center and S&W's Performance Center team up to build an entry-level long-range... Gunsite's Ed Head reviews the Ruger American/Robar Scout Rifle. This helps support the blog and allows me to continue to create free content that’s useful to hunters like yourself. The .270 Win has a relatively flat trajectory itself, but the 270 WSM had a small, but definite advantage in this area. The 7mm WSM is similar to the .300 WSM with the case necked down to handle .284" bullets. The 7mm Remington Magnum is one of the most popular centerfire rifle cartridges in North America and is likely among the Top 10 best selling rifle cartridges in the United States. Glad to see the WSM family got some attention. When you consider the fact that the 270 WSM has significantly more case capacity than the older .270 Winchester and that both cartridges have the same maximum SAAMI pressure, it shouldn’t be surprising that the 270 WSM is actually capable of shooting the same weight bullet at a higher velocity than the .270 Winchester. The same goes for guns: rifles chambered in 7mm Remington Magnum are extremely popular and very commonly in the United States. So with that said, there’s absolutely nothing wrong with the 300 WSM either I understand why other hunters prefer the 300 WSM. As you can see, the two cartridges have almost identical amounts of recoil with the 270 WSM in this particular example actually having a tiny bit less free recoil energy than the .270 Winchester. Both loads are compared when fired from a Winchester Model 70 Featherweight rifle. Though it’s not quite as commonly used as cartridges like the .270 Winchester, 7mm Remington Magnum, or .300 Winchester Magnum, the .338 Winchester Magnum is still quite popular. The 7mm Winchester Short Magnum very likely does gain some accuracy benefit from its shorter and fatter powder column. Looking at it that way, it’s not surprising that the 7mm WSM is likely on its way out. That’s is because the 325 Winchester Short Magnum load in question uses about 12% less powder than the .338 Win Mag. Normally you’d be right and the rifle for the standard length cartridge would be either a little longer and heavier or virtually the same size and weight. However, 200 grain, 225 grain, and 250 grain bullet weights are most common for .338 Win Mag factory ammo. Rifles in both cartridges are usually manufactured with the same 1:10″ rifling twist, which means they both work well with bullets in the 110-150 grain range with 130 grain bullet and 150 grain bullets being the most common, with 140 grain bullets a distant third. ballistics. Once again, there’s a good selection for both, but rifles chambered in 270 WSM aren’t quite as common and are usually more expensive. These two cartridges present an interesting case though. Is it significantly more accurate than the .338 Winchester Magnum? That’s not to say that the .338 Win Mag won’t work for that sort of hunting because it certainly will. Both of these cartridges became popular in the shooting world because of their ballistic characteristics, especially the trajectory, and the low recoil while still can bring down medium and even larger sized game. It's still at the gunsmith with some final mods to the ejection port. LMAO. This is not a hard and fast rule though and it’s sometimes possible to find rifles chambered in 7mm Remington Magnum that can accommodate another round or two compared to those chambered in 7mm WSM. CVA Paramount Muzzleloader: Read This Before You Buy One! That’s not meant to be a knock on the Winchester Short Magnum line either. First, let’s talk about the history of the Winchester Short Magnum (WSM) line of cartridges and what the company was trying to achieve. Your write ups always offer very practical and useful information. The 7mm Remington mag is well established but not so versatile as the.30-06. The 7mm-08 case is just slightly longer than the parent .308â2.035 inches vs. 2.015 inchesâbut maintains the same 20-degree shoulder of the .308 Winchester. Note: No company currently manufactures rifles chambered in 7mm WSM. On paper, the Winchester Short Magnums are very closely matched with their standard length cousins. As illustrated in the chart, .270 WSM Winchester Short Magnum rounds - on average - achieve a velocity of about 3240 feet per second (fps) while 7mm-08 Remington rounds travel at a velocity of 2830 fps. With that in mind, the 325 WSM is a better choice for situations where very large and tough game like sambar deer or moose are likely to be encountered at close range. Now that we’ve covered the basic history and design of the Winchester Short Magnum cartridges, let’s see how they compare to the .270 Winchester, 7mm Remington Magnum, 300 Winchester Magnum, and .338 Winchester Magnum. 145 Posts . I’ve always thought the 270wsm was similar to the 7mm Mag. While rifles chambered in both cartridges are manufactured with both 22″ and 24″ barrels, the shorter 22″ barrel length is more common with the .270 Winchester and the longer 24″ barrel is more common with the 270 WSM. However, though the .300 Win Mag (like the 7mm Rem Mag) is derived from the .375 H&H Magnum and uses a fatter case than cartridges like the .270 and .30-06, the 300 WSM still has a much fatter case with less taper and a steeper shoulder angle (35 degrees vs 25 degrees). Remember: we’re talking about accuracy under practical hunting conditions, not benchrest shooting where a tiny improvement in group size can make a big difference. Since the 270 WSM uses a significantly shorter cartridge, you’d probably expect rifles in that cartridge to be shorter and lighter than rifles chambered in .270 Winchester. After all we wouldn’t want to hurt someone’s sensitive feelings. You got to figure one or two should survive. I used the Hornady Ballistic calculator and ShootersCalculator.com to compare trajectory, wind drift, and recoil for the cartridges. As fans of the Winchester Short Magnum cartridges like to point out, the 325 Winchester Short Magnum likely does gain some accuracy benefit from its shorter powder column. 270 vs 280 vs 280 AI vs 7mm Rem Mag Ammo Selection. Not surprisingly, many sportsmen and women were a little skeptical about the line of Winchester Short Magnum cartridges introduced in the early 2000s that claimed to offer even better performance than these legendary centerfire rifle hunting cartridges. However, as long as you can find a rifle and ammunition combination that function reliably and shoot accurately together, if using one of those cartridges improves the confidence of the shooter to a large enough degree, then by all means start hunting with a Winchester Short Magnum cartridge. Discussion Starter ⢠#1 ⢠Nov 18, 2013. more energy at that range. A bit more than the 7mm Rem. Unfortunately, the future isn’t looking very bright for that cartridge right now. that. For instance, a current production Winchester Model 70 Sporter chambered in 325 WSM weighs about 7.25 pounds and has an overall length of 44.24″. It’s not a gigantic difference, but this often means that the 270 WSM has a definite advantage in terms of external ballistics and sometimes slightly less recoil, but that the .270 Winchester is more often available in shorter, lighter, and easier to handle rifles. Though Winchester advertises a 24″ long barrel and a 7.25 pound overall weight for each cartridge in this particular Model 70, the rifle chambered in 300 WSM is 1/2″ shorter overall. The release of the .270 Winchester in 1925 in the Winchester Model 54 rifle saw the beginning of the American love affair with velocity, as well as the laying of a solid foundation for the American bolt-action sporting rifle.At the time, the lever gun held court in the hunting fields, though through the writings of Mr. OâConnor, change was on the wind. In today’s world, better to sugar coat it than to sound like we may be mocking. Seventy-six years after the .270 broke cover Winchester launched the .300 WSM, and a year later in 2002 Winchester unveiled the .270 WSM. Additionally, while neither cartridge has a belt, the .270 Winchester uses a traditional rimless design while the 270 WSM has a rebated rim. However, the 300 WSM is capable of attaining almost the same performance as the .300 Win Mag while using less powder. This results in a little bit less recoil. However, the Winchester Short Magnum cartridges all use a much fatter case without a belt that more closely resembles the case used by the old .404 Jeffery as well as the later Winchester Super Short Magnum (WSSM) line of cartridges. If you prefer a shorter, potentially lighter rifle, that’s slightly faster cycling and easier to carry, but still has magnum performance, then go with the 300 WSM. This specific model weighs 7.25 pounds when chambered in both 7mm WSM and 7mm Rem Mag. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.This is the first instance where we’ve seen the Winchester Short Magnum serve up similar performance with an appreciable reduction in recoil. Factory loads for the 7mm WSM and 7mm Rem Mag often use the exact same bullets fired at virtually the same muzzle velocity. However, the .270 Win.’s long case body feeds easily in most rifles while the WSM has a reputation for being more finicky. On the other hand, that’s not a gigantic advantage in favor of the 270 WSM either. However, though Browning, Kimber, and Savage all manufactured 325 WSM rifles at one point, only Winchester currently offers current production rifles in the cartridge (the Model 70 and XPR at this point). On the other hand, the Winchester Short Magnum cartridge does not have a gigantic advantage in either category either and there’s actually a smaller difference in the ballistics of the 7mm WSM vs 7mm Rem Mag than there is with the 270 WSM vs 270 Winchester. For all intents and purposes, there is no difference between them ballistically and both cartridges will really do a number on most species of big game. This is not the case for the 7mm WSM though. Due to the long running popularity of the .270 Winchester, there’s a plethora of quality bullets to choose from for both cartridges. Far Zero for the WSM load and the 140 grain 7mm load is identical, while FZ of the heavy WSM load is 10 yards longer than the 160 grain 7mm. I think we can agree that most hunters and shooters in North America are probably familiar with the venerable .270 Winchester, 7mm Remington Magnum, .300 Winchester Magnum cartridges. Lbs.) However, the 325 Winchester Short Magnum doesn’t have a closely related standard length cousin that’s widely used in North America. Additionally, the company also advertised that the shorter case used by the WSM cartridges resulted in superior accuracy and less recoil. I joined a deer lease this year and I'm hunting on a pipeline. The 270 WSM is one of the few calibers that actually has a ballistic advantage over the standard caliber of its own. The .300 Winchester and .300 Winchester Short Magnum are suited for very similar hunting situations, with one small caveat. Remember: we’re talking about accuracy under practical hunting conditions, not benchrest shooting where a .1″ or .2″ improvement in group size can make a big difference. The two cartridges (along with others like the 7mm Mauser, 7mm-08, 7mm Weatherby, 280 Remington, 280 Ackley Improved, and 7mm Remington Ultra Magnum) use the same .284″ bullets. And, if you're a 7mm fan, don't overlook the deadly 7mm-08 Remington. I’m not sure if it cracks the Top 10 best selling rifle cartridges in the United States each year, but it’s likely in the Top 15 or Top 20. Except the .270 WSM offers its performance from a shorter action, and does it with a shorter barrel. Additionally, the .300 Win Mag has a shoulder moved further forward than the 7mm Rem Mag. The road to the famous Remington 700 rifle was paved with classics like the models 725 and 30s. That being said, it’s probably a little bit more expensive and, while there’s a good variety of ammo for the cartridge, the .270 Winchester usually has a bigger selection regardless of where you go. What about when comparing bullets of the same or very similar weight? Below you can see the differences between the 325 Winchester Magnum and the .338 Winchester Short Magnum in terms of external dimensions. Not surprisingly, this results in some interesting ballistic comparisons. Though Winchester advertises a 24″ long barrel and a 7.25 pound overall weight for each cartridge in this particular Model 70, the rifle chambered in 325 WSM is 1/2″ shorter overall. I'm struggling with the same issue. However, the distance from the case head to the datum line on the shoulder is longer for the 7WSM, preventing accidental chambering or firing of the .284" 7mm bullet in .270 WSM's .277" bore. The generally better feeding and overall reliability of most 7mm Remington Magnum rifles is a big plus as well. The differences in external dimensions between the .270 Winchester and 270 WSM obvious in the photo below. Additionally, the 7mm Remington Magnum is a traditional belted magnum while the 7mm WSM has a rebated rim and no belt. Reloading components for the .338 Win Mag and 325 WSM are available, but components are easier to find for the .338 Win Mag. While there is a big overlap in bullet weights the 325 WSM and .338 Win Mag can use (both cartridges are commonly loaded with bullets in the 180 grain to 250 grain range), the .338 Win Mag generally leans a little heavier than the 325 WSM. With this load, the .270 WSM generates roughly 250 additional foot-pounds of energy over its competitor at the muzzle when both cartridges are fired from 24-inch barrels. Both rifles in this case also have a 3 round magazine, so there’s no advantage there with either cartridge. On the other hand, the majority of 7mm WSM factory loads use bullets in the 140-162 grain range and 140, 150, and 162gr bullets are pretty common. .300 Win Mag ammo is probably a little bit easier to find, it’s not by much and you’re likely to find a good selection of ammo for both cartridges regardless of where you go. The new .270 WSM and 7mm WSM are based on the original short, fat, beltless .300 WSM case, which was developed by Winchester and Browning sui generis for the new WSM series. I guess riflemen are becoming While the performance of the two cartridges at reasonable hunting ranges is very similar, the logistics of getting a good rifle, quality ammunition, or even reloading components for the .388 Win Mag are so much simpler for that cartridge when compared to the 325 WSM. That small reduction in recoil is also particularly helpful here as well. For those reasons, the .300 Win Mag actually has significantly more case capacity (around 10-15% more, depending on the manufacturer) than the 300 WSM. Like all the other Winchester Short Magnum cartridges, the 325 WSM is specifically designed to fit in a short action rifle instead of a standard length action like the larger .338 Winchester Magnum. This is one of the tougher aspects of using the 325 WSM: there’s not a gigantic variety of factory ammo or a large number of bullet choices for hand loaders to choose from. That said, while the 325 WSM is quite popular in some circles, it is not nearly as widely used and cannot hold a candle to the .338 Win Mag in that area. The modern “magnum era” began in earnest with the introduction of the 7mm Remington Magnum and .300 Winchester Magnum cartridges during the 1960s. .270 versus 7mm Rem Mag. While both cartridges are really too light for hunting extremely large, thick skinned dangerous game like cape buffalo, they will both fit the bill for hunting Grizzly or Alaska Brown Bear. Likewise, ammunition for the .270 WSM is less likely to be found on every store shelf, but it’s relatively widely available, and many sporting goods stores—even relatively small stores—often stock .270 WSM. Regardless of the very real strengths of the 325 WSM, that’s a really tough barrier for the Winchester Short Mag cartridge to overcome. That heavier and more aerodynamic bullet retains energy better at long range and the edge in kinetic energy grows as the distance increases. The 325 WSM is an attractive choice for hunters in the niches I described above and those that use the cartridge generally seem to absolutely love it. This makes sense since the 7mm WSM is specifically designed to fit in a short action rifle instead of a standard length action like the 7mm Rem Mag. Not saying the .270 WSM is a 'wrong' choice, just not what I would chose if doing it again. Additionally, the .300 Winchester Magnum is a traditional belted magnum while the 300 WSM has a rebated rim and no belt.Just like with the 7mm WSM vs 7mm Rem Mag, even though the 300 WSM uses a case with a larger diameter, the .300 Win Mag also uses a relatively large diameter case itself and is significantly longer. While rifles like the Winchester Model 70 were produced in that chambering for several years, I’m not aware of any rifles currently manufactured in 7mm WSM. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. Is the 325 WSM capable of excellent accuracy? With heavy (150 grain) bullets the difference is about 100 fps, hardly enough to place the WSM in a different league than the original .270 Win. The .270 Winchester is one of the most popular centerfire rifle cartridges in North America and is very likely among the Top 10 (maybe Top 5) best selling rifle cartridges in the United States each year. Inside of 200 yards no advantage. However, their .555″ case diameter is larger than those used by the 7mm Rem Mag and .300 Win Mag (.513″) as well as the .270 Winchester (.470″). The Hornady .300 Win Mag shoots a little bit flatter due to its faster muzzle velocity, but the difference between them is so small that it’s probably not even worth considering. However, the 300 WSM could have an advantage on those sort of hunts because it’s available a smaller and easier to carry rifle. Just like with the 7mm WSM vs 7mm Rem Mag and 300 WSM vs 300 Win Mag, even though the 325 WSM uses a case with a larger diameter, the .338 Win Mag itself has a relatively large diameter case and is significantly longer. All RifleShooter subscribers now have digital access to their magazine content. The .300 Winchester Magnum is extremely popular and is consistently among the Top 10 best selling rifle cartridges in the United States each year. The .300 Win Mag is a bit more widely adopted, but you probably won’t have any issues finding a nice rifle chambered in 300 WSM either. Those factors result in this particular 300 WSM load having about 7% less free recoil than the .300 Win Mag. What about accuracy of the 7mm WSM vs 7mm Rem Mag? Following the immediate success of the .300 WSM in 2001, the .270 and 7mm WSM were introduced in 2002. The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards. However, even though the .338 Win Mag (like the 7mm Rem Mag and .300 Win Mag) is derived from the .375 H&H Magnum and uses a fatter case than cartridges like the .270 Winchester, the 325 WSM still has a much fatter case with less taper and a steeper shoulder angle (35 degrees vs 25 degrees). ballistics. However, Winchester likely made an attempt at doing just that, but since the case is optimized for the 300 WSM, they probably were not getting the desired performance with a .338″ bullet and opted for a .323″ compromise instead. Both cartridges normally use bullets in 150-230 grain range. The .270,7mm and .300 WSM,s make the .30-06 look a little anemic.I don't understand why exactly but the .270 became fairly popular and the 7mm didn't catch on.I have two of them and they are decent.I had one reamed further in the freebore to use heavier bullets and keep base out of powder capacity.Of course the .270 doesn't have that problem because of limited choice in bullets. The .300 Winchester Magnum and 300 Winchester Short Magnum cartridges have essentially the same external ballistics. Ok let’s give them the benefit of the doubt and say they like availability and reliable feeding. Both loads are compared when fired from a Winchester Model 70 Featherweight rifle. October 28, 2013 In theory, this results in improved accuracy for the shorter case. Second, both cartridges use the same .277″ diameter bullets. This is not always the case and some 270 WSM rifles feed exceptionally reliably of course, but it’s likely more of an issue with that cartridge that’s not often encountered with the 270 and its longer, slimmer, and more tapered case. Is it significantly more accurate than the 7mm Remington Magnum? Specifically, 180 grain, 200 grain, and 220 grain bullets are most popular for 325 WSM factory ammo. The 325 WSM also has a slightly higher maximum SAAMI pressure than the .338 Winchester Magnum (65,000psi vs 64,000psi).Unlike all the other comparisons in this article, the 325 WSM and .338 Win Mag use different sized bullets. Tom Beckstrand and Neal Emery of Hornady highlight the 6MM Creedmoor ammo. For those reasons, sporting goods stores usually carry ammunition for both cartridges. By running slightly less than max loads I've had cases go 18 times. The table below compares the recoil produced by two Nosler hand loads (available here and here) with ballistics roughly comparable to the 140gr loads above for those cartridges when fired from a Winchester Model 70 Featherweight rifle. Do the WSM cartridges offer tangible benefits to hunters and shooters? Is the 270 WSM capable of excellent accuracy? (All further WSM introductions will be based on this case as well.)
