Barnes Bullets ARC Grain 50-Count TAC-TX Boat Tail Features The Barnes Bullets 22 ARC TAC-TX Boat Tail is a special purpose expanding all-copper bullet optimized specifically around AR platform rifles. Because AR rifles typically run shorter carbine length barrels they produce reduced muzzle velocity compared to a standard-length barrel which can hurt terminal performance with conventional bullets. To solve that Barnes added a larger tip that allows more fluid to enter the nose on impact and modified the bullet cavity to maximize expansion even at these lower velocities. The boat tail design also improves the bullet s ballistic efficiency downrange helping it retain velocity and accuracy at extended distances. Built entirely from copper with no lead core this 70 grain .224 inch diameter bullet tracks straighter through barriers than lead-core designs and retains significantly more of its original weight after impact. That weight retention translates directly into deeper more reliable penetration on target a trait Barnes bullets are known for across their product lines. Fifty bullets ship per box giving handloaders enough projectiles to work up and refine a load for their 22 ARC rifle. For reloaders building dedicated AR-platform 22 ARC ammunition the Barnes Bullets TAC-TX Boat Tail is available for sale at GrabAGun.
