Description
300 Blackout 123 grain FMJ ammo from Magtech gives rifle shooters a high-volume range load in a bulk 1,000-round case. Each 300BLKB round uses a 123-grain full metal jacket bullet with brass casing and Magtech’s small rifle primer construction.
Magtech lists this load at 2,230 fps with 1,359 ft-lbs of muzzle energy from a 16-inch test barrel. The FMJ projectile makes it a practical option for target shooting, range training, plinking, and regular practice in compatible .300 AAC Blackout firearms.
Each case includes 20 boxes of 50 rounds, making it easy to stock one consistent practice load for multiple range sessions. The brass cases also add value for shooters who save reloadable brass after practice.
Compared with 300 Blackout soft point, hollow point, or subsonic loads, this Magtech 300BLKB option is better positioned as supersonic FMJ range ammunition. For related options, browse 300 AAC Blackout Ammo, Bulk Rifle Ammo, and Magtech Ammo.
