The .25-45 cartridge from the Sharps Rifle Company is a caliber that will interest many shooting enthusiasts. This cartridge uses the same basic case of the 5.56mm NATO, so it can be adapted to AR actions chambered for this popular defense caliber. More importantly, the Sharps .25-45 cartridge retains the 23-degree case shoulder of the 5.56mm, meaning it will feed reliably from existing magazines designed for this caliber. The ammunition will come with three different projectiles: an 87-grain Speer Hot-Cor and 87-grain FMJ that generate 3,000 fps and 1,738 foot-pounds of energy at the muzzle, as well as a 65-grain Varmint load that leaves the muzzle at 3,300 fps and produces 1,571 foot-pounds of energy at the muzzle.
