For hunters running classic British battle rifles or sporting .303 platforms, Remington Core-Lokt 303 British ammo delivers field-proven terminal performance. This is jacketed soft point ammunition — 180-grain projectiles designed to expand reliably on impact while retaining enough mass to penetrate vitals on deer, elk, black bear, and similarly sized game. Muzzle velocity sits at 2460 feet per second, generating 2418 foot-pounds of energy at the muzzle. The Core-Lokt bullet uses a tapered copper jacket mechanically locked to the lead core, controlling expansion and preventing core-jacket separation during penetration.
Load Profile
Each round is loaded in new brass cases with non-corrosive Boxer primers, so you can reload the spent cases after your hunt. Remington manufactures this ammunition in the United States. The 180-grain bullet weight represents the traditional standard for .303 British, balancing sectional density and downrange energy retention. Supersonic velocity at the muzzle transitions to subsonic around 800 yards depending on atmospheric conditions, but effective hunting range tops out well before that point — most shooters zero at 100 or 200 yards and hold over for longer shots within ethical limits.
