The Sport Utility line features Inceptor's patent-pending polymer-copper RNP bullet technology. The RNP bullet version of the polymer-copper bullet is the Round Nose PRECISION, a solid-core injection-molded copper-polymer bullet that rivals any competition-level target shooting cartridge. The Inceptor RNP projectile is the ideal choice for both the professional shooter looking for extreme accuracy, due to near-perfect concentricity and almost undetectable weight variation between bullets, and the amateur reloader/shooter looking for a low-recoil, precision target round to hone their craft. This is not loaded ammunition.
