Speer .50 Caliber 300-Grain Uni-Cor Total Metal Jacket Bullets, 50-Box

The Speer .50 Caliber 300-Grain Uni-Cor Total Metal Jacket Bullets, 50-Box (brand part no. 4490) are a 300-grain .50 Caliber bullet from Speer built as a Uni-Cor total metal jacket (TMJ) projectile for handloaders. Speer’s Uni-Cor process completely encases the lead core in a seamless copper jacket, unlike a conventional FMJ that leaves the base exposed, for a cleaner-burning, more consistent bullet. Reloaders load this bullet for high-volume range and target practice, including indoor ranges, seating it over a charge worked up for their own rifle or pistol. As a component bullet, it ships without powder or primer, ready for the reloading bench.
