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

These rounds of ammunition are BLEMS. They may have cosmetic defects such as surface scratches, dings or light tarnish. These cosmetic defects do not affect performance.

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.
