For lever-action hunters, the Remington Core-Lokt 30-30 Winchester ammo remains the standard—a 170-grain jacketed hollow point engineered for controlled expansion on medium game at woods ranges. The 30-30 Winchester cartridge was developed in 1895 as the first North American sporting round designed for smokeless powder, and it remains the most popular lever-action hunting caliber in production. This load exits the muzzle at 2200 feet per second with 1827 foot-pounds of energy, balancing trajectory and terminal performance for whitetail, hogs, and black bear inside 200 yards. The Core-Lokt bullet uses a tapered copper jacket locked to the lead core, preventing jacket separation on bone or heavy muscle while expanding reliably at 30-30 velocities.

Built for the Box

The Remington Core-Lokt bullet applies a mechanical locking process during manufacture—the jacket is drawn over the core, then crimped at the base to prevent the two components from separating during expansion. The 170-grain jacketed hollow point features a deep cavity that initiates expansion on impact, while the thick jacket walls retain mass through heavy tissue. Brass cases are drawn to SAAMI minimum wall thickness for consistent resizing over multiple reloads, and Boxer primers allow straightforward decapping. Each round is loaded to 2200 fps from a 24-inch test barrel—expect 2100–2150 fps from typical 20-inch lever guns.

The Numbers

This load pairs with any 30-30 ammo rifle chambered to SAAMI specs—Marlin 336, Winchester 94, Henry H009, Mossberg 464. Zero at 100 yards for a 3-inch drop at 150 and 10-inch drop at 200, keeping point-of-impact inside vital zones on deer-sized game through typical woods engagement distances.
