The 143rd NRA Annual Meetings & Exhibits are just days away, and the first new product we’ve heard about could prove to be revolutionary. Federal Premium Ammunition is striving to redefine modern in-line performance with its new Trophy Copper muzzleloader bullet, which features one of the company’s latest innovations: the B.O.R. Lock MZ system.
Designed to provide top-notch accuracy in a non-sabot design that’s easy to load, scrubs fouling from the breech and ensures consistent bullet seating, the B.O.R. Lock MZ system’s foundation is a polymer cup that’s permanently attached to the bullet base. Yes, you read that right—it stays attached. This isn’t a sabot, but it’s not a belted bullet, either. The force of ignition pushes the cup forward onto raised bands along the bullet shank, expanding its diameter. That engages the rifling and seals the bore, optimizing velocity and accuracy.
“B.O.R. stands for ‘Bullet Obturating Ramp.’ The walls of the polymer cup get pushed up and out, into the rifling,” said Bryan Peterson, Federal Premium’s Senior Product Development Engineer. “You get an excellent seal—and that means better ballistics and downrange performance.”
