The Hornady 60 grain TAP urban runs very well in my 14.5" 1-7 twist and 16" 1-8 twist carbines. Great price and service from Miwall.
Hornady Ammunition 223 Rem 60 Grain TAP Urban - 200 Rounds - CASE
The Hornady® 223 Rem 60 gr. TAP Urban® offers high velocity and performance similar to that of other polymer tipped Hornady® 223 bullets. The 60 gr. bullet offers similar retained weight and penetration to the 55 gr. TAP Urban, and is the heaviest polymer tipped bullet acceptable for 1:12" twist weapons. The heavier 60 gr. bullet transfers more energy to the target for enhanced terminal performance.
