Armscor .223 Rem 55gr FMJ Ammo – 20 Round Box

Description

The Armscor FAC2231N is a straightforward choice for anyone running regular practice sessions or breaking in a new build. You get 20 rounds of solid, dependable .223 loaded with a 55-grain full metal jacket bullet—the standard configuration that works across AR-15s and bolt guns alike. Made right here in the USA, these rounds fire consistently at around 3,050 feet per second with about 1,135 foot-pounds of muzzle energy, giving you a flat trajectory out to reasonable distances and minimal recoil.

What to Expect From Armscor's .223 Load

This ammunition uses quality brass casings with Boxer primers and is completely reloadable if you reload. The non-corrosive powder and primers mean you won't have to worry about accelerated rust inside your barrel after a range day. Real-world experience shows you'll get 1.5 to 3 MOA accuracy at 100 yards with standard optics and a stable rest—that's exactly what you should expect from bulk training ammo.

Built for Volume Shooting

The 55-grain FMJ bullet won't expand, which is the whole point for range work. It feeds cleanly through magazine-fed rifles, cycles reliably, and produces reasonably light carbon fouling compared to some alternatives. Users report solid groups without failures to feed, which matters when you're trying to focus on fundamentals instead of troubleshooting. The reloadable brass adds value if you're already set up for reloading, and the factory consistency means you won't have wild velocity spreads making you chase wind.

Range Shooting and Training

This is where Armscor's 55-grain load shines. It's built for high-volume practice, trigger training, and getting rounds downrange without breaking your ammo budget. The compact 20-round box fits cleanly in a range bag, and you can stack multiple boxes for longer sessions. If you're just getting started or running through hundreds of rounds during competitions or training courses, this load keeps things simple and affordable.
