400LEG.165AMMO

Engineered for unmatched power, precision, and terminal performance, we are proud to introduce the 400 Legend as our newest addition to our ammunition lineup. This unique bullet construction delivers exceptional weight retention, ensuring the projectile maintains its mass even after encountering heavy bone. It generates more kinetic energy at 350 yards than a 10mm Auto 180-grain bullet has at the muzzle, while producing about 24% less recoil than the 450 Bushmaster.
 
Compatible with all factory magazines, this ammunition supercharges your 400 Legend: delivering unrivaled performance and reliability. Our proprietary all-copper 165-grain AR bullet is loaded into Peterson's Cartridge Companies new 400 Legend brass. Each cartridge case offers exceptional durability and can be reloaded up to 20 times, ensuring consistent performance and long-lasting value for shooters who wish to reload the spent casings. This ammunition is offered in convenient 20-round packs and housed in a sleek, reusable snap-lid container.
 
Notes: Casings have discoloration due to annealing of the case mouths which is not pictured in the product image above. Savage rifles may produce 50 fps higher velocities due to their unique barrel dimensions. Compatible with all factory magazines.

    Haven’t had a chance to put them to paper

    Posted by Brian Kearns II on Dec 11th 2025

    After a call to Bear creek ballistics, and a discussion with the gentleman over the phone I ordered what round was best for my rifle. Package arrived in timely manner and the rounds look superb. I can’t wait to get to the range and see what they do. I have a feeling I’ll be a customer for a long time. After I try these I’m sure I’ll be ordering bullets and brass to see what real potential my new 400 has!

    Great ammo

    Sight in was a breeze. Consistent. Harvested 2 deer around 150yd. Great results. Both dropped in their tracks.

    400 legend

    Posted by Marty Chapo on Nov 20th 2025

    I got two boxes of this ammunition prior to Michigan opening day. It shot 4 inches higher than my 215 Gr bullets. I reset my scope and put 3 bullets almost touching on bulls eye at 100 yds. Opening day I shot 8 point buck that I called in. He was at 65 yds facing me. Bullet took out 3 ribs, heart, lung and ended up in rear hind quarter. After watching all the videos about lead bullets leaving lead in meat I intend to eat I stopped using lead several years ago. These fit the bill. They cost more but I think they are worth it.

    Ran into my AR 15, works excellent definitely can tell the difference between shooting normal ammo and this. I will be using it this year for my hunting.

    Stuff is worth it. Just amazingly consistent. Overlapping three rounds at 70 yards from a BCA AR-15 with Walmart scope. To think, I spent $73 on 20 Rounds to shoot out of a $400 gun. Will do it again.
