This Rangemaster label ammo is optimal for any AR-15 or other rifle chambered for 5.56x45. The round’s 55 grain FMJBT projectile puts its performance on par with any military M193 load. A hard gilding metal jacket may inhibit terminal expansion, although terminal fragmentation is highly likely within 190 yards. The FMJBT’s boat tail base reduces in-flight drag; that keeps the bullet flying faster so it can stick to a flat trajectory as it remains supersonic until around 718 yards.
Prvi Partizan does not cheapen their bullets by putting steel in their cores or jackets, which makes this true nonmagnetic ammunition. They also outfit their new production rounds with non-corrosive Boxer primers and repeatedly reloadable brass cases. The company’s Quality Management System is structured in accordance with ISO 9001:2008 standards, and they’re widely regarded as one of the best sources of range ammo.
