First, the .300 Win Mag is a lot longer. 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. The same goes for guns: rifles chambered in .270 Winchester are among the most commonly produced centerfire rifles in the United States. Taken together, these factors all maximize the case capacity of the WSM cartridges, even though their overall length of 2.86″ is still short enough to fit in a short-action rifle. But compairing the 300 Win mag to the 300WSM is not even fair as the 300 Win mag hold alot more powder and the 300 Win mag will out run the WSM every time if the barrel is at least 24" ,the same goes for the 7mmWSM versus the 7mm Rem mag. 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 . 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. So, depending on the exact rifle model in question, it’s likely that one chambered in 325 WSM will be somewhat shorter and handier as well as potentially a little lighter. 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. However, 200 grain, 225 grain, and 250 grain bullet weights are most common for .338 Win Mag factory ammo. That’s not a gigantic difference, but it’s certainly not nothing either. In fact, the difference in published velocity is often smaller for the 300 WSM vs 300 Win Mag than the 7mm WSM and 7mm Rem Mag. The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 WSM Winchester Short Magnum vs 7mm-08 Remington ammo rounds. Once again, the 7mm WSM has a little bit less wind drift, but it’s an extremely small difference between them that’s due entirely to the slightly faster muzzle velocity of the Winchester Short Magnum cartridge. Use A Thermacell To Stop Bug Bites While Hunting & Camping. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. 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. This is not a guarantee of course and some 300 WSM rifles feed quite reliably. 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. 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. Interestingly enough, a .323″ bullet diameter is exactly halfway between the .308″ bullets used by the 300 WSM and .300 Win Mag on one hand, and the .338″ bullets used by the .338 Win Mag on the other. I personally prefer the .300 Win Mag, but you should also know that my affinity for that cartridge is due in part to my preference for Ruger rifles (which are not currently manufactured in any WSM cartridge). Again, probably not. 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. This is an incredibly small practical difference. Winchester claimed these new cartridges could meet or even exceed the ballistic performance of comparable standard length cartridges like the .270 Winchester, the 7mm Remington Magnum, and .300 Winchester Magnum. What about accuracy of the 7mm WSM vs 7mm Rem Mag? 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 larger game like caribou, elk, moose, red stag, kudu, and eland with great results and I personally lean towards these bigger .30 caliber cartridges as opposed to the .270 and 7mm cartridges previously discussed for an Africa, Canada, or New Zealand hunting safari. 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). The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above.

Is it significantly more accurate than the 7mm Remington Magnum? 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. Killed deer out to 400 yds., a 12' croc in Africa, a 350# WV bear at 48 yds. 270 WSM vs 270 Winchester They’re both great cartridges and I’d personally say that the 325 WSM is the second most appealing choice out of the Winchester Short Magnum line (behind the 300WSM). The 7mm is a belted cartridge and the 300wsm is a rimmed cartridge. 7mm WSM vs 7mm Rem Mag Does the difference between the two cartridges in terms of accuracy make a difference for most hunters under typical conditions? 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. 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. The situation with rifles in is pretty similar. The increase in length of the .300 WM over the .300 WSM is greater than the increased wideness of the case of the .300 WSM. Prospects for new rifles chambered in 7mm Winchester Short Magnum are already pretty dim and it’s possible that things will also be heading that way soon with factory ammo. 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. Overall, the .338 AccuBond load is the best here with the 325 WSM AccuBond coming in a relatively close second. 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. This shouldn’t be surprising though because the 300 WSM is specifically designed to fit in a short action rifle instead of a standard length action like the larger .300 Winchester Magnum. X, and a 175 # WV bear at 279 yds. 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. This is illustrated in the table below comparing Federal Premium and Hornady factory ammunition loaded with 140gr Trophy Bonded Tip (.430 BC) and 162gr ELD-X (.631 BC) bullets in 7mm WSM and 7mm Rem Mag. Is the 325 WSM capable of excellent accuracy? The situation is a little different with the Winchester factory load and the 325 WSM has the edge in retained energy. The answers to the above questions really depend on the rifle, ammunition, and shooter in question though. 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 exact size of the rifle action (which includes the locking bolt, firing pin, etc.) 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. Make sure you subscribe to The Big Game Hunting Podcast and follow The Big Game Hunting Blog on Facebook, Instagram, Twitter, and YouTube. 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. The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards. What about when comparing bullets of the same or very similar weight? Re: 6.5 Creedmoor vs 7mm WSM hunting rifle 7wsm becouse of the elk. However, both 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. 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 generally better feeding and overall reliability of most 7mm Remington Magnum rifles is a big plus as well. Winchester claims a muzzle velocity (MV) of 3,225 ft/s with a 140 grain bullet for their 7mm WSM cartridge; the claimed muzzle energy (ME) is 3,233 ft. lbs. The WSM, in the proper loadings, is pretty close to a 300 win mag. J Mac said: Currently I am shooting an older 7mm REM in need of an upgrade. Though I doubt that a well placed shot on an animal with an extra 200 feet per second of velocity or 250 foot pounds of energy will make a big difference, it won’t necessarily hurt either and I can see why someone would want that extra power, especially when hunting game like elk and moose. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges. The table below compares the recoil produced by two Nosler hand loads (available here and here) with ballistics roughly comparable to the 130gr loads above for those cartridges when fired from a Winchester Model 70 Featherweight rifle. Our website lists special deals on 9mm Ammo, 10mm Ammo, 45-70 Ammo, 6.5 Creedmoor ammo, 300 Blackout Ammo, 10mm Ammo, 5.56 Ammo, Underwood Ammo, Buffalo Bore Ammo and more special deals on bulk ammo. The .300 Winchester Magnum and 300 Winchester Short Magnum cartridges have essentially the same external ballistics. Of course the 300 WSM case is used for the longer neck. Both rifles in this case also have a 3 round magazine, so there’s no advantage there with either cartridge. Note: these are not the only broad categories of rifle actions. CVA Paramount Muzzleloader: Read This Before You Buy One! Please email us if you have questions about any of our product listings. Is this really the case? They’re both great cartridges, but I’d probably lean towards the .270 Winchester. 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. Both cartridges normally use bullets in 150-230 grain range. Rifles in both cartridges are also extremely common. Ok let’s give them the benefit of the doubt and say they like availability and reliable feeding. In fact, depending on the exact brand of factory ammo we’re talking about (like Barnes VOR-TX), the 300 WSM may have a faster published velocity. 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. 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. However, while that may well contribute somewhat to improved accuracy, there are many other factors that influence accuracy to a much larger degree. Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. This results in a little bit less recoil. I went with the 325 to try something different for a change. All told, both are wonderful cartridges for hunting some of the larger species of North American big game or African plains game. Additionally, the .300 Win Mag has a shoulder moved further forward than the 7mm Rem Mag. If I were you, I would go with either the 300 WSM or build a 7mm-300 WSM because of the brass. Is the 300 WSM capable of excellent accuracy? When the 7-300WSM came out in 2009, the Brits were way ahead of us. 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. Of course, this is not always the case and some rifles chambered in 7mm WSM rifles feed quite reliably, but it’s more of an issue with that cartridge that’s not as often encountered with the 7mm Rem Mag and its longer, slimmer, and more tapered case. 12 % less free recoil than the 7mm is a traditional belted Magnum while the.338 Magnum...
