Federal Law Enforcement Tactical TRU 223 Remington Ammo 55 Grain Nosler Ballistic Tip ammo review offers the following information;Federal’s Tactical TRU line of ammunition gives your semi-automatic rifle the power it needs to see you through even the darkest of times. This 223 Rem cartridge is loaded with Nosler’s 55 grain Ballistic Tip, a projectile optimized for quickly neutralizing a human-sized threat. The bullet’s polymer tip is tough to avoid deforming while stored in a magazine, and upon impact drives inward to deliver expansion and devastating energy transferral. The Ballistic Tip’s jacket is tapered to control that expansion, and possesses a heavy base that acts as a platform upon which wider expansion can take place and further averts accuracy-harming deformation.
