The 350 Legend (9x43mm) is a straight-walled cartridge introduced in 2019 by Winchester Repeating Arms primarily for deer hunting in states with specific ammunition restrictions. At 2300 fps, this is the highest muzzle velocity, production, straight-walled ammunition available. Bullet weights of 125-280 grain give this round a 150-300 yard lethal range for white tail deer, hogs, and coyotes. The 350 Legend uses a standard 223/556 bolt carrier group but requires magazines designed for the 350 Legend round.
