This 351 Winchester Self-Loading ammunition is loaded with a 0.351" diameter Speer Hot-Cor jacketed flat point bullet. This load is meant to replicate old/original ballistic performance of the now obsolete cartridge. Speer Hot-Cor Flat Nose Bullets are designed for safe use in firearms with tubular magazines. These bullets also hold together better because the Hot-Cor process eliminates the lead oxide layer that's found between the core and jacket of conventional "cold core" bullets. This translates into a bullet that offers deeper penetration and greater expansion that is needed for taking larger game.
Note: This ammunition is loaded with smokeless powder and should only be fired in firearms suitable for smokeless loads.
