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.
