.350 Legend Specs

The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) accepted the Winchester .350 Legend as a new cartridge and chamber standard in early 2019, but there is still some confusion. Here’s a direct link to the .350 Legend and technical specs and drawings, courtesy of SAAMI.

The cartridge uses a modified, .223 Rem. shell case with a 1.71-inch length and a bullet diameter of .357 inch. “The .350 Legend is a high-performing, straight-walled cartridge that dominates in velocity, energy, recoil and affordability,” said Winchester Ammunition Vice President of Sales and Marketing Matt Campbell. “Winchester is dedicated to innovation and it’s paramount that we continue to deliver meaningful, technology-driven products that have a tremendous impact on the hunting and shooting sports industry.”

Here’s a look at two new .350 Legend loads from Browning.

 “SAAMI member ammunition and firearm companies are driven by technological innovation,” said Randy Bimson, director of technical affairs and technical advisor for SAAMI. “Winchester’s .350 Legend cartridge brings a fresh look and innovation to a very mature cartridge category opening up new options to both the hunter and recreational shooter.”

There are a variety of companies offering the ammunition. For obvious reasons Winchester was the first, Hornady joined in and just recently introduced a 165-grain FTX load (the company also offers a 170-grain InterLock) and Federal has several loads to choose from. Browning rolled out a line in January, 2020, at the SHOT Show. If your local sporting goods store doesn’t have it in stock, I suggest Wideners. I rely on it for ammo when testing guns. Good folks and reliable service.

• Maximum Average Pressure: 55,000 psi

• Overall Length: 2.125 to 2.260 inches

• SAAMI Tested Bullet Weight: 145-grains

• Velocity at the Muzzle of a 16-inch Barrel: 2,250 fps

• Muzzle Energy: 1,630 ft-lbs.

SAAMI has set the firearms and ammunition industry’s technical standards since it was founded in 1926 at the request of the Federal Government—a move that standardizes pressures and dimensions for an added layer of safety in the industry. Its track record makes the dedication of the organization and its members obvious.

Winchester has also made brass available for reloading.

Finding the right cartridge for long distance can be a challenge, but the experts I interviewed provided some sound advice.
