STEADFAST .300 BLK 220gr TMJ Subsonic Reman is constructed utilizing a Berry’s Bullets total metal jacket, spire point projectile loaded in remanufactured/repurposed .223/5.56 casings with mixed headstamps.
These brass rifle casings are remanufactured. Some of these casings may have cosmetic defects such as surface scratches, dings or light tarnish. These cosmetic defects do not affect performance.
Velocity: ~1020 fps in a 16 inch bbl with 1:8 twist / ~920 fps in a 16 inch bbl with 1:7 twist / ~900 fps in a 10″ bbl with 1:7 twist
Recommended for barrels with a twist rate of 1:8 or faster – e.g., 1:8, 1:7, 1:6, 1:5.
