While the belt was unnecessary on most of those cartridges, it spelled high performance to many hunters, and for that reason it sold lots of rifles and ammunition through the years. Magnum and would not whimper a bit if the rifle I carry is chambered for one of the .416s from Remington, Weatherby, or Rigby. The .300 SAUM is why my Remington Model Seven feels like a .308 but hits like a .300 H&H. It has the accuracy of the 6.5 Creedmoor and the power of the 300 Win Mag… a nice combination! Stuff the.300 with about 73 grains of IMR 4831 powder, and it should kick that bullet out at 3,150 fps. Though both cartridges utilize .308″ bullets, the .300 Win Mag is also better suited for using heavier bullets in the 200-220 grain range than the .30-06. While it is true that a .300 magnum is a bit much for bumping off a skinny, little, 100-pound southern whitetail deer at ranges we commonly find in thickly forested country, try telling that to hunters who head to Alberta, Canada, where a buck can push 400 pounds on the hoof and the only shot you get after a week of freezing your fanny off may be 400 yards or farther in a strong sidewind. I am saying all this to say that whether or not a cartridge has a belt on its case is of no importance. When it comes to magnum cartridges of .30 caliber, there seems to be no middle ground among hunters. Both died very quickly. Mag., an additional pound of powder is required for each 1,400 rounds loaded. Mag. David Fortier talks with Jeff Hoffman of Black Hills Ammunition about the evolution of the .308 Win. Like most of his other magnum cartridges, this is based on a blown-out .300 H&H Magnum case, using the signature Weatherby double-radius shoulder. Introduced in 1925, the .300 H&H is the oldest of the .300 magnums, but it's still one of the best. I believe more experienced hunters will agree that the question is too complicated for such simple answers, and accurate conclusions can be made only after a close look at a few details. This is where the similarities end. Bottom line is, you are in good company regardless of which .300 magnum you choose. Here is the G&S Online Killing Power Formula used to compile this list: Energy at 100 yards (in foot pounds) x Sectional Density (taken from reloading manuals) x cross-sectional Area (in square inches) = Killing Power Score at 100 yards. Magnum cartridges than for the same number of .300 WSM cartridges. Left to Right: .300 H&H Magnum, .30 Newton, .300. I have never been faced with the unpleasant task of going into the thick stuff to finish off a wounded bear, but if it ever happens, I would want to be shooting a heavier bullet of larger caliber. Consider cartridges/loads scoring below KPS 11.0, at whatever you consider their maximum effective range to be, as small game and varmint cartridges. 175 Gr. Others consider them too much for deer and not as good as cartridges of larger calibers on larger game. Even so, I do not consider any .300 magnum to be the ultimate brown bear cartridge. The .300 Weatherby Magnum is a fast, hard-hitting cartridge, driving a 180-grain bullet to a muzzle velocity of 3250 fps, for over 4,000 ft.-lbs. There is no comparison between the two except to say that they are both .30 caliber. What 308 and 300 Win Mag are both great at. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bulle Perhaps it is time we sift through the rumors and seek out a fact or two. (These two are approximately equal in killing power at 200 yards.). When it comes to magnum cartridges of .30 caliber, there seems to be no middle ground among hunters. Refine by Caliber: .300 Win. – Gun brand doesn’t matter. Additionally, it’s an extremely accurate cartridge that may even have a slight edge on the .30-06 in that regard. A 100 yard KPS score somewhere in the 30s is probably a reasonable figure for most Class 3 game, although less powerful cartridges/loads have long been used successfully. The .300 Weatherby is not renowned for extreme accuracy, but Boddington has found it plenty accurate enough. Mag. A KPS of 30 corresponds well with a Hornady HITS score over 901, which the experts at Hornady consider the minimum for use on large game. I worked up a load that is pushing a 150 grain bullet at 3620 fps. It is into this market that Weatherby unleashed the world’s fastest production 6.5 mm cartridge—the 6.5-300 Wby. You can always load down the 300 mag to 308 levels of performance, on deer, but you dont need to do so, given the 25% reductionof recoil by the gas op BAR. Recoil: Recoil is far less in a 308 than a 300 win mag. Tracks were so fresh I could have sworn they were still smoking. In addition to being easy to work with, the 6mm PPC is incredibly accurate, but had benchresters stayed with the .222 Rem., they would still be setting new accuracy records simply because actions, barrels, bullets, powders, and shooters have continued to improve through the years. Having spent the time and effort to devise a rifle cartridge killing power formula that has a positive correlation with actual results in the field, it seemed appropriate to use that formula to compare the killing power of various hunting rifle cartridges and loads. Subscriber Services. Personally,I'd never bother with more power than the alloy framed 308 BAR offers. When first introduced in 1944, this cartridge developed a reputation for “excessive” recoil and unpredictable results on game. Fourth Place: .300 Weatherby Magnum, 65.0 Points. Around 70 years later, and the round is still consider one of the world's blistering hot magnums. Closest to it in propellant stinginess is the .300 H&H Magnum at 43 fps, while the .300 Winchester Magnum averaged 41 fps.

I have been using rifles chambered for belted cartridges since the 1960s, and not once have I discovered anything to complain about. Long experience has shown the .44-40 200 grain/1310 fps MV load (KPS 11.0) and traditional .25-35 117 grain/2230 fps MV load (KPS 11.9) are adequate 100 yard deer cartridges, provided the hunter drives the bullet directly into the vitals. Copyright 2017 by Chuck Hawks. Note: A more comprehensive rifle cartridge killing power comparison list with more calibers and loads can be found on the Member Side Tables, Charts and Lists page. But when it all comes together, an accurate rifle chambered in .300 Weatherby Magnum, suitable projectiles and optimum technique, well that’s something. But I do not for one minute think they have made other .300 magnums obsolete. Whether or not the slightly better efficiency of the .300 WSM is worth more than a hill of beans depends on how many rounds are loaded each year. Mag., but it starts to increase as we move up to the faster .300 Weatherby Magnum. case, necked down to accept a .264-cal. Hornady .300 PRC (left) and .300 WBY.300 Weatherby Magnum vs. Hornady .300 PRC. Another long held belief of mine is the .30-30/150 grain load is a more powerful 100 yard cartridge than the .243 Win./100 grain load. ISS Prop House gives us the rundown on the guns used in Enemy at the Gate. You will also get the same response from professional hunters in Africa who have long been, and probably always will be, extremely fond of the .375 H&H Magnum as well as another belted number called the .458 Winchester Magnum. Short Magnum .30-30 WCF ... 308 Norma Mag 338 Norma Magnum. Ammo By Manufacturer Qualified Professional Ammo. It also tends to confirm some long held beliefs. When it comes to hunting larger game, a great many Class 3 animals have been taken by careful shots using cartridges/loads such as the .30-30/170 grain, 6.5x55/140 grain and 7x57/160 grain.

We have also been given several reasons why one of the new breed of super-short magnum .30 cartridges is the thing to have, while long, slim .30 magnums are out of style. Looking at it another way, when the three cartridges are loaded to maximum velocities with 180-grain bullets, the .300 WSM burns an average of 3 grains less powder than the .300 H&H and 5 grains less than the .300 Win. I am sorta surprised that quite a few people think the 257 may be a better choice. It was for this reason that I purchased the Weatherby Mark V 6.5-300. Roy Weatherby already had experience with other custom cartridges such as his own .270 Weatherby Magnum when he created the .300 Weatherby. Refine by Caliber: .300 Weatherby Magnum .300 Win.

Most orders ship within 24 hours (excludes firearms). The .308 Winchester performs best with bullets from 150 gr up to 168 gr. The Alaskan Game Department considers the .30-06 shooting 220 grain bullets (100 yard KPS 54.6) a reasonable minimum for hunting Alaskan grizzly and brown bears, which are Class 4 (dangerous) animals. I actually prefer the .375 H&H. Therefore, I have chosen to use a minimum KPS of 12.5 for Class 2 game in many of my articles. Remington specifically states that their Managed Recoil .30-30 load is a 100 yard deer cartridge. For the .300 Win. Under those conditions, one shot at a bruin is all you will likely get, and it had better be a good one. The 6mm PPC wins most benchrest matches today simply because it is the cartridge most benchrest shooters shoot. The cartridge was developed in response to a US Army military contract in 1959. The Winchester .350 Legend is a no-nonsense whitetail thumper tailored for rifle hunters in... A half-century in the making, the new DGX Bonded is Hornady's best-ever dangerous-game bullet. holds about 48.6 grains of water. James Tarr runs through the 3-Second Headshot drill. It hurts a bit to write this particular comparison, because I’m really partial to the .300 WBY. We ping steel with a .300 WinMag at over a mile. The joys of handloading are many, and one of them is sharing the experience with a novice. Then came a new breed of magnum cartridges without a belt, and suddenly that little band of brass just forward of the extraction groove of a case had more critics than Michael Moore at a soap-makers convention. Very sensibly, Winchester did not attempt to compete with the far more powerful and much harder-kicking.300 Weatherby Magnum. Hunting rifles, even those capable of half-MOA accuracy would never know which cartridge they are chambered for. For a fascinating, two part analysis in depth of the G&S Online rifle cartridge killing power formula and its ramifications, see the articles The G&S Online Rifle Cartridge Killing Power Formula: Implications and Applications and Determining The Effective Killing Range of Rifle Cartridges by Gary Zinn. Match. Our perception of recoil is influenced by many things, including the shape of a riflestock and how well its pad soaks it up, but if the various .30-caliber magnums are fired in identical rifles, some are more comfortable to shoot than the others under certain circumstances. Was shooting Weatherby 257 Magnum, purchased First Lite in 6.5 300, bore sighted, straight out of box first 3 shots 1 inch high with grouping touching each other. So what it comes down to to me is .300 Win Mag vs 300 Weatherby. As you can see, when the maximum loads of five .300 magnum cartridges listed in six reloading manuals were compared, the .300 WSM produced an average of 45 fps in velocity for each grain of powder used. Mag. We look at the futuristic .450 Bushmaster and how it compares to the tried and true .45-70. I am not alone with this opinion. While the 257 weatherby mag is perfectly capable of killing elk I would consider it to be way down the list of fine elk rounds. This video supplies more detailed information which I have gathered on the 300 Weatherby 165 gr ammo performance than in any of my prior videos. On the other hand, most experienced North American elk hunters would probably suggest full power .270 Winchester loads (KPS 35+) as a practical minimum. The author has taken a lot of big game, including Alaska brown bear, with the Remington Model 700 in .300 Ultra Mag, and he likes both the rifle and the cartridge. This means you have the option to read your magazine on most popular phones and tablets.
