STEADFAST .300 BLK 110gr HP Varminter is constructed utilizing a Sierra Bullets hollow point, jacketed lead projectile loaded in new brass casings.

Velocity: ~2250 fps in a 16" bbl with 1:8 twist, ~2220 fps in a 16" bbl with 1:7 twist

Recommended for barrels with a twist rate of 1:7 or slower – e.g., 1:7, 1:8, 1:9, 1:10.
Barrels with a twist rate faster than 1:7 (e.g., 1:6, 1:5) may cause deformation of the bullet. If deformation occurs, accuracy will be greatly-inhibited. If using a suppressor, the deformed bullet may damage the suppressor.
