Description
Federal American Eagle 300 Blackout 220gr 500rd box Ammunition
This 300 Blackout ammo case holds 500 rounds of Federal American Eagle 220gr subsonic OTM — enough consistent inventory to dial in reliable, suppressed cycling before you’re relying on it at the range.
Product Description
A 300 Blackout ammo case built specifically for suppressed shooting solves one problem: staying under the speed of sound so the suppressor can do its job without a sonic crack undercutting it. This Federal American Eagle load uses a 220-grain Open Tip Match (OTM) bullet at a listed 1,000 fps — comfortably subsonic and built for 300 Blackout subsonic suppressed setups — for quiet, consistent range work.
Because subsonic loads generate different pressure curves than supersonic ammo, cycling reliability depends on your specific gas system, barrel length, suppressor, and magazine. A 500-round case gives you the volume to actually test that — not just a single 300 Blackout ammo box, but enough rounds across all 25 boxes to confirm your setup runs clean before you count on it.
Each round is loaded in the U.S. with non-corrosive boxer primers and virgin brass, so the fired cases are reloadable if you handload your own subsonic ammo.
