The 350 Legend was released in 2019 and created solely by Winchester Repeating Arms Ammunition division, known now as simply Winchester Ammunition. The 350 Legend is a legend in its own right because it is one of the few cartridges that has no parent cartridge. It does have the same diameter as the .223 Remington cartridge but that is where the similarities of the two rounds start and end. This straight-walled cartridge was developed for hunting where states had strict regulations on straight-walled deer hunting rounds. The 350 Legend is a product of the Ammunition industry responding to ridiculous government regulation and overreach. Without oddball laws on hunting with necked cartridges, straight-walled cartridges like the 350 Legend cartridge would likely not exist. The performance of the round was designed to deliver high lethal terminal energy on deer at ranges out to 200 yards. The 350 Legend sits in an area of its own where at 200 yards it outpaces 300 Blackout, 30-30 Winchester, and 223 Remington in energy on target. The closest comparison for foot-pounds on target for the Legend is the 300 Blackout round which comes in at 790 ft-lbs at 200-yards. The 350 Legend clocks in at 903 ft-lbs at 200-yards. As you can see it’s no slouch and the .350 legend doesn’t just barely edge out the 300 blackout round either.
The.375 Winchester is a modernized version of the.38-55 Winchester, which was first introduced in 1884 as a black powder cartridge. In 1978, the.375 Winchester cartridge and the Winchester Model 94 "Big Bore" lever-action rifle were launched. It was lauded at the time of its release as a cartridge capable of firing far larger bullets than the.30-30 Win. and in a rifle that weighed only 6.5 pounds.
It was designed by U.S gunmaker Charles H Ballard to be a modern take on Winchester's much older ammo variants. Only Winchester produces a.375 loadings, which is advertised as a 200-grain flat nose Powerpoint bullet that shoots at a realistic 2100fps. The Powerpoint bullet breaks 1800fps at just 80 yards from this velocity, beyond which this bullet design struggles to expand. It is feasible to outperform factory loads by up to 100fps when using manual loads.
The 375 Winchester produces muzzle velocities that are not as high as some of the more recent additions, including factory and hand loads. It can be a slow killer if shot placement isn't perfect. It's worth noting that the cartridge is designed to extend down to impact velocities of 1600fps. The.375" barrel is very broad, and the cartridge's hefty bullets are capable of producing relatively deep penetration. The.375 is able to deliver consistent results by combining a large bullet diameter with hefty flat pointed bullets. If you are looking to be hunting white-tailed deer in the timber, then the 375 Winchester is a good choice.
