.300 AAC BLK STEADFAST 125gr PCT ATC Self Defense is constructed utilizing a Precision Component Technologies aluminum-tipped, solid copper, fracturing projectile loaded with all new components.

Lead-free

Velocity: 2250 fps in a 16 inch bbl 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.
