STEADFAST .300 BLK 150gr TREX is constructed utilizing a Maker Bullets expanding, polymer-tipped, solid copper projectile loaded in new brass casings.

The polymer tip increases the ballistic coefficient and initiates dramatic expansion upon impact.

Lead-free

Velocity: ~1650 fps in a 16 inch bbl with 1:8 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.
