Description
50 BMG 660 grain FMJ ammo from Ammo Inc gives long-range shooters a brass-cased range load in a 100-round case. Each 50BMG660FMJ-A10 round uses a 660-grain full metal jacket bullet with Boxer-primed brass casing and Ammo Inc Signature rifle-ammunition construction.
Retailer-listed ballistics show this load at 2,900 fps with 12,327 ft-lbs of muzzle energy. The FMJ projectile makes it a practical option for long-range target shooting, range use, and firearm function confirmation in compatible .50 BMG rifles.
Each case includes 10 boxes of 10 rounds, making it easier to store, transport, and manage high-value .50 BMG ammunition by the box. The reloadable brass cases also add value for shooters who save brass after range use.
Compared with match-specific or specialty .50 BMG loads, this Ammo Inc 50BMG660FMJ-A10 option is better positioned as a full metal jacket range load for shooters who want bulk quantity and consistent basic performance.
