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 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. Anyhow, I like the concept of the wsm family of cartridges. 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. 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 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. We offer a 100% Authenticity Guarantee on all products sold on our website. 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. wusses when it comes to recoil. Before we get started, I have an administrative note: Some of the links below are affiliate links. 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 are also capable of outstanding accuracy in the right hands. 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. Even so, they have different strengths and weaknesses and the 7mm Rem Mag vs 300 Win Mag debate is still going strong over 50 years later. They’re both solid performing cartridges, but I’d personally choose the 7mm Remington Magnum over the 7mm Winchester Short Magnum. Recoil of the 300 WSM should be pretty much the same as the 300 Win Mag. 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. The .300 Winchester and .300 Winchester Short Magnum are suited for very similar hunting situations, with one small caveat. As illustrated in the chart, .300 WSM Winchester Short Magnum rounds - on average - achieve a velocity of about 3080 feet per second (fps) while 7mm-08 Remington rounds travel at a velocity of 2830 fps. To put this into perspective, a Boeing 737 commercial airliner travels at a cruising speed of 600 mph, or 880 fps. Both cartridges also offer a substantial increase in power, both in terms of bullet frontal surface area and kinetic energy, over the 300 Magnums as well. While I would not describe the 7mm WSM as a rare or hard to find cartridge, it’s not especially popular or widely available. They’re both outstanding cartridges and I’d say that the 300 WSM is the best designed out of the Winchester Short Magnum line. Use A Thermacell To Stop Bug Bites While Hunting & Camping. This specific model weighs 7.25 pounds when chambered in both 325 WSM and .338 Winchester Magnum. Again, probably not. After all, the .300 Win Mag is capable of excellent accuracy itself and is generally very highly regarded in that area as well. However, the 300 WSM is capable of attaining almost the same performance as the .300 Win Mag while using less powder. Those factors result in this particular 300 WSM load having about 7% less free recoil than the .300 Win Mag. 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. 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. After all, fans of the Winchester Short Magnum cartridges like to point out the benefits of the shorter and fatter powder column. 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. For example, 4-5 round magazines are pretty common with the .270 Win, but 3 round magazines are about all you’ll find with the 270 WSM. However, while that factor may well contribute to better accuracy, there are many other factors that influence accuracy to a much larger degree. That is to say, .270 WSM Winchester Short Magnum bullets travel 3.7 times the speed of a 737 airplane at cruising speed, while .300 Winchester Magnum bullets travel 3.4 times that same speed. Additionally, the Winchester Short Magnum Cartridges all have a case with very minimal taper and a 35 degree shoulder. I guess riflemen are becoming 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, while that may well contribute somewhat to improved accuracy, there are many other factors that influence accuracy to a much larger degree. 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. It’s also possible to find other rifles where there’s an even bigger difference in size and weight between the two cartridges. After all, fans of the Winchester Short Magnum cartridges like to point out the benefits of the shorter and fatter powder column. 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 WSM and 325 WSM also have the benefit of doing all of the above with a modest decrease in recoil compared to the .300 Win Mag and .338 Win Mag while the 270 WSM offers a definite improvement in velocity over the .270 Winchester. 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 photo below does a great job of showing the differences in external dimensions between the 300 Winchester Magnum and the 300 Winchester Short Magnum. 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. So, while the rifle chambered in 300 WSM is not significantly lighter, it’s a tiny bit shorter and handier. That small reduction in recoil is also particularly helpful here as well. 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. Have you ever considered the 270 WSM? 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. Once again, the 270 WSM has a slight advantage over the .270 Winchester in this area. Additionally, the 7mm Remington Magnum is a traditional belted magnum while the 7mm WSM has a rebated rim and no belt. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. Re: 6.5 Creedmoor vs 7mm WSM hunting rifle 7wsm becouse of the elk. What about accuracy of the 270 Winchester vs 270 WSM? Lbs.) 7mm WSM vs 7mm Rem Mag Is it significantly more accurate than the .338 Winchester Magnum? However, while those that may well contribute to better accuracy, there are many other factors that influence accuracy to a much larger degree. This specific model weighs 7.25 pounds when chambered in 270 WSM and 7 pounds when chambered in .270 Winchester. I love the 6.5's but the Elk at a distance the 7mm's have it. You got to figure one or two should survive. 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. The 325 WSM has similar ballistics to the magnum action, medium bore 8mm Remington Magnum and 8×68 S cartridges. Compare the 180 gr 30-06 verses the 150 gr 270 WSM and you get the same or possibly less recoil and better ballistics all around except energy with the 270 WSM. What about accuracy of the 7mm WSM vs 7mm Rem Mag? 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 rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. First, the .270 Winchester is significantly longer. The generally better feeding and overall reliability of most 7mm Remington Magnum rifles is a big plus as well. 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. Is the 300 WSM capable of excellent accuracy? 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. The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above. Both cartridges are also well suited for hand loaders and reloading components for the .300 Win Mag and 300 WSM are widely available. So with that said, there’s absolutely nothing wrong with the 300 WSM either I understand why other hunters prefer the 300 WSM. The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards. That’s not a gigantic difference, but it’s certainly not nothing either. 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. 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. 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. Is it significantly more accurate than the .270 Winchester? At the same time, the 300 WSM is the most popular Winchester Short Magnum cartridge and is also extremely commonly used as well. As you can probably guess, there is very little difference in the trajectories in the two cartridges. That is to say, .300 WSM Winchester Short Magnum bullets travel 3.5 times the speed of a 737 airplane at cruising speed, while 7mm-08 Remington bullets travel 3.2 times that same speed. Virtually every major brand of ammo is available in 7mm Rem Mag. The 7mm is a belted cartridge and the 300wsm is a rimmed cartridge. The 300 Winchester Short Magnum likely does gain some accuracy benefit from its shorter powder column. 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. 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. Once again, there is essentially no difference between the recoil of the two cartridges though. They rounded out the lineup with the 325 Winchester Short Magnum in 2005. Both cartridges use cases derived from the long, belted .375 H&H Magnum. Generally speaking, the higher the muzzle energy, the higher the stopping power. I currently have hunting and target rifles in .308, 30-06, 300 WSM, and 300 Ack. 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. We offer cheap ammo and bulk ammo deals on the most popular ammo calibers. Note: these are not the only broad categories of rifle actions. This is obviously not great news for fans of the 7mm Winchester Short Magnum and does not bode well for the future of the cartridge. This means that it’s possible to build a short action rifle that’s a tiny bit shorter and lighter than an otherwise identical rifle with a standard length action. As a quick aside, the choice of a .323″ (8mm) bullet diameter for the 325 WSM was a pretty big surprise to the shooting industry, which was expecting Winchester to release a 338 WSM instead. However, regardless of the firearm in question, rifles chambered in .270 Winchester can usually hold an extra round or two in the magazine since that cartridge has a slimmer case. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. Finally, it’s also nice to have that extra round or two of ammunition in your magazine available if you end up needing it one day. This helps support the blog and allows me to continue to create free content that’s useful to hunters like yourself. Anyhow, good luck with your choice. if your going to shoot deer at that distance go with the 300wsm.the 7mm-08 just isn't going to cut it.its a nice little round but i wouldn't push it much past 400 yards on deer.both of them have great bullet selection and can be very accurate but the 300wsm has the ability to push heavier bullets down range.if you're recoil sensitive then you can go with a muzzlebrake but thats not always the best option.i have had both cartridges chamered in several different setups and … Hunters like yourself and less recoil big game hunting Adventures LLC | all Rights Reserved have similar external!
