Speer 1605 Hot-Cor 277Cal 150gr Spitzer Soft Point projectiles deliver incredibly reliable all-range accuracy and terminal performance for medium game hunters. The Hot-Cor process involves pouring molten lead into the jacket during construction, which maximizes consistency and virtually eliminates jacket-core separation. This 150-grain Spitzer profile ensures a flat trajectory and reliable expansion upon impact, making it a versatile choice for harvesting medium to large game across a variety of shooting conditions. Defensive Application Designed for deep penetration on game, these bullets present a high over-penetration risk in residential environments and are not recommended for home defense.
