Hornady‘s Frontier line in .300 AAC Blackout (brand part no. FR401) loads a 125-grain full metal jacket bullet built for shooters who put serious volume through their AR-platform pistols and short-barreled rifles.

The full metal jacket bullet is a straightforward, no-frills design built to feed reliably rather than expand, keeping cost per round down for high-round-count range days. For .300 Blackout shooters who want dependable training ammo, this rifle ammunition is built to run.
