As such, the following is for comparative information purposes only and should not be used to make precise predictions of the trajectory, performance, or true ballistics of any particular .300 WSM Winchester Short Magnum or 7mm-08 Remington rounds for hunting, target shooting, plinking, or any other usage. The 7mm WSM also has a higher maximum SAAMI pressure than the 7mm Remington Magnum (65,000psi vs 61,000psi). 325 WSM vs 338 Win Mag Additionally, the .300 Win Mag has a shoulder moved further forward than the 7mm Rem Mag. Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. 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. 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. However, the same rifle in .338 Win Mag is advertised at 7.75 pounds and 46.75″ long overall (because it has a 26″ barrel instead of a 24″ barrel like the 325 WSM rifle). First, both have the same maximum SAAMI pressure of 65,000psi. The case is based off a .300 WSM with a narrowed neck to fit .284 inch bullets on a .321 inch neck and the parent case is the .404 Jeffery. Many of the most popular centerfire rifle cartridges in the United States, like the .270 Winchester and .30-06 Springfield (both of which have an overall length 3.34″), require the use of what is commonly referred to as a “standard action” or “long-action” rifle. 7mm wsm vs 7mm/300 wsm After my last what to do the the 708 post i started looking at these two options .From what i understand the only real advantage of the 7mm /300 is the longer neck , Is it really worth the hassle of necking down or is the standard 7mmWsm fine . Once again, there is essentially no difference between the recoil of the two cartridges though. This makes sense since the 270 WSM is specifically designed to fit in a short action rifle instead of a standard length action like the .270 Winchester. Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. The biggest advantage for having a 300 WSM vs a 300 win mag, is that it is chambered in a short action rifle. For the majority of hunters, the .338 Winchester Magnum is the more practical choice. For example, so called “magnum actions” are even longer than standard actions. As you can probably guess, there is very little difference in the trajectories in the two cartridges. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer The table below compares the recoil produced by two Nosler hand loads (available here and here) firing 200gr Nosler AccuBonds at virtually the same velocity: 2,885fps for the 300 WSM and 2,910 for the .300 Win Mag. 6.5 Creedmoor vs 243 Winchester Review & Comparison, 6.5 Creedmoor vs 7mm-08 Remington Review & Comparison, 6.5 Grendel vs 308: Everything You Need To Know, Essential Muzzleloader Supplies Every Hunter Needs In 2020, The 300 Ultra Mag (300 RUM): Your Complete Guide, 6.8 SPC vs 6.5 Grendel: What You Need To Know, 6.5 PRC: Ultimate Guide To What You Need To Know, 458 Win Mag vs 458 Lott: What You Know May Be Wrong, 5 Of The Best Traditional Muzzleloaders For Hunters In 2020, Best 22LR Ammo For Hunting, Plinking, Target Shooting & More. By and large, the 270 WSM, 7mm WSM, 300 WSM, and 325 WSM are all capable of excellent accuracy and essentially duplicate the performance of comparable standard length cartridges while fitting in a short action. Lightweight handy rifles giving magnum performance should have become more popular. At the same time, the 300 WSM has most closely lived up to the hype, which explains why it’s far and away the most popular of the bunch. 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). At reasonable shooting ranges, there’s very little practical difference between them ballistically and both cartridges will really do a number on both species of game. Recoil is very reasonable with a SSK brake. Especially when hunting at shorter ranges (inside 200 yards), the 325 Winchester Short Magnum offers virtually the same performance as the .338 Win Mag, but with considerably less recoil. However, both Nosler and Winchester manufacture their Trophy Grade and Power Max Bonded lines of ammunition in both cartridges. Both will work exceptionally well on game ranging from whitetail, mule, and fallow deer all the way up to elk and moose out to several hundred yards. The .338 Winchester Magnum and 325 Winchester Short Magnum cartridges have similar, external ballistics, especially at ranges inside 300 yards. 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. None of them have covered any new ground. What about accuracy of the 7mm WSM vs 7mm Rem Mag? Book an incredible Africa hunting safari here. The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above. It also carries a tad more energy out to longer range and is capable of excellent accuracy. CVA Paramount Muzzleloader: Read This Before You Buy One!
