Book an incredible Africa hunting safari here. Maximum pressure obtained from SAAMI (p23, 24, 28, 30, 31, and 32). What about accuracy of the 300 Win Mag vs 300 WSM? 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. 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. However, there are many, many other factors that influence accuracy more than that one trait. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. Finally, while the two cartridges use the same 7mm bullets (.284″ diameter) and there is a big overlap in typical bullet weights for each cartridge, the 7mm WSM normally uses lighter bullets than the 7mm Remington Magnum. This specific model weighs 7.25 pounds when chambered in 270 WSM and 7 pounds when chambered in .270 Winchester. The 7mm WSM also has a higher maximum SAAMI pressure than the 7mm Remington Magnum (65,000psi vs 61,000psi). lbs.) I've only shot one deer but that was with the .270WSM from 275 yards.My brother has shot alot more deer than I have and he uses a 7mm Rem Mag.Last year he shot a doe from 310 yards with his.I would go with the 7Mag since the ammo is alot easier to find.Both will kill a deer dead as a doornail though. That heavier and more aerodynamic bullet retains energy better at long range and the edge in kinetic energy grows as the distance increases. In that same vein, those fat, stubby 7mm WSM cartridges with their very steep shoulder angle can sometimes present feeding problems. 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. I have both. per sec. Like all 7mms, they can fire bullets as light as 100-grains and as heavy as 180-grains. Mag. 300 Win. More on this in a minute, but it’s worth noting that for those two AccuBond loads in particular, the 325 WSM has almost 95% of the kinetic energy of the .338 Win Mag and has essentially the same trajectory out to 200 yards. Glad to see the WSM family got some attention. 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. Maybe more, but can't remember. Does the difference between the two cartridges in terms of accuracy make a difference for most hunters under typical conditions? Probably not. However, other cartridges, like the 6.5 Creedmoor and .308 Winchester (which have overall lengths of 2.825″ and 2.81″ respectively), are about a half inch shorter and will therefore fit into what’s commonly known as a “short-action” rifle. The .338 Winchester Magnum and 325 Winchester Short Magnum cartridges have similar, external ballistics, especially at ranges inside 300 yards. Like I said, they’re all well designed and very capable hunting cartridges. The .300 Winchester Magnum and 300 WSM (along with the .30-30 Winchester, .308 Winchester, .30-06 Springfield, .300 Remington Ultra Magnum, .300 Remington Short Action Ultra Magnum, 300 PRC, and .300 Weatherby) use the same .30 caliber bullets. Now, the Winchester Short Magnum cartridges were not the first commercially produced short magnums. So, while the 7mm WSM is faster on paper, the two cartridges have essentially the same velocity for all intents and purposes. Factory loads for the 7mm WSM and 7mm Rem Mag often use the exact same bullets fired at virtually the same muzzle velocity. However, both the 7mm Remington Magnum and 7mm Winchester Short Magnum cartridges are capable of excellent accuracy in the right hands and will get the job done under most circumstances if the shooter is up to the task. It probably doesn’t crack the Top 10 list, but it’s close. This results in less recoil. If I was in the market to get one of the two calibers, then it would be the 7 mag for me also. Mag. Both are also capable of outstanding accuracy in the right hands. However, the 270 WSM has a very fat case with minimal taper and a much steeper shoulder angle (35 degrees vs 17.5 degrees).For those reasons, the 270 WSM is unique among the Winchester Short Magnum cartridges for actually having significantly more case capacity (around 10-20% more, depending on the case manufacturer) than its standard length cousin. It’s just that it doesn’t offer a significant improvement in power over the 325 WSM at close range, but still has more recoil. While it’s certainly nice to have if possible, a the difference in a theoretical 1.25″ vs a 1.5″ group most likely won’t matter much while actually hunting at reasonable ranges. First, let’s talk about the history of the Winchester Short Magnum (WSM) line of cartridges and what the company was trying to achieve. The .270WSM is more forgiving on my shoulder. In theory, this results in improved accuracy for the shorter case. more than the 160 grain 7mm load. 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). The same goes for guns: rifles chambered in .270 Winchester are among the most commonly produced centerfire rifles in the United States. and the 7mm would be in 140 grain, and the .270wsm in 130g. 150 grain, 165 grain, 180 grain, 190 grain, 200 grain, and 220 grain bullets are the most popular.Similar to the case with the 7mm WSM vs 7mm Rem Mag, the 300 WSM and .300 Win Mag factory loads often fire the exact same bullet at virtually identical velocities.

The 7mm Remington mag is well established but not so versatile as the .30-06. 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. With this in mind, designers at Winchester Repeating Arms elected to build a line of cartridges that could fit in a short length action with the goal of achieving similar performance to popular standard length cartridges. 7mm Rem. 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. 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. What about when comparing bullets of the same or very similar weight? Comparing the .270 with the 7mm Remington magnum is like comparing grits and white cornmeal. 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. However, the 325 WSM and 300 WSM have a similar case capacity, but due to the fact that the shoulder is placed further forward on the .300 Win Mag, the .338 Win Mag actually has a little less case capacity than the .300 Win Mag. However, the 300 WSM is capable of attaining almost the same performance as the .300 Win Mag while using less powder. It also carries a tad more energy out to longer range and is capable of excellent accuracy. Both will work exceptionally well on deer sized game out to several hundred yards. The buck I killed with my 7mm-08 at 541 yards was just as dead. However, the two cartridges have some similarities as well.
