Speer Hot-Cor 45 Caliber (.458 Diameter) 350 Grain Flat Nose Bullets - Box of 50

Speer Hot-Cor 45 caliber rifle bullets deliver the consistency and accuracy that serious hunters and reloaders demand. These .458 diameter, 350 grain flat nose projectiles are engineered using Speer's proven Hot-Cor process—molten lead poured directly into the jacket to ensure uniform construction and reliable performance from round to round. Whether you're handloading for a .458 Winchester Magnum, .458 SOCOM, or another large-bore rifle chambering, Hot-Cor bullets give you the precision foundation that separates decent loads from truly dialed-in ammunition.

The flat nose profile is built for controlled expansion and deeper penetration on medium to large game, making these bullets a trusted choice for hunters working at extended range or in brush. Because they're manufactured to exacting standards, you'll spend less time sorting and inspecting components and more time at the range or in the field confident that each shot will perform as expected.

Reloaders who value batch-to-batch consistency and the ability to work with premium component lines choose Speer Hot-Cor bullets. This box contains 50 projectiles, enough for a solid block of handloads or to refresh your inventory between seasons.
