6mm Arc Velocity Vs Barrel Length, 56) so it retains velocity better after leaving the barrel.
- 6mm Arc Velocity Vs Barrel Length, This is true whether you shoot it from a 12", 18" or 24" barrel. The velocity retention ensures the bullet can hit targets over 500 yards with significant force. This maneuverability makes short to medium-length barrels better for combat, home defense, and other situations where speed and mobility are important. 504 subscribers in the 6mmARC community.
