400 Legend – 210 Gr SP – Remington (R21307) – 200 Rounds

This 400 Legend Remington Core-Lokt load (R21307) gives straight-wall hunters a hard-hitting rifle cartridge with proven soft point performance. Remington loads it with a 210 grain Core-Lokt Soft Point bullet. That bullet uses a classic cup-and-core design with the jacket mechanically locked to the lead core. As a result, it expands reliably and keeps enough weight to drive through deer-sized game.

Remington rates this load at 2,250 fps. Retail ballistics list it at 2,360 ft-lbs of muzzle energy. Therefore, this round brings serious field power while staying inside the straight-wall category. That matters for hunters in states or zones that require straight-wall rifle cartridges. It also gives shooters a strong option without jumping into heavy magnum recoil.

The 400 Legend has a practical role. It hits harder than many smaller straight-wall rounds. Meanwhile, it still handles well in modern hunting rifles. The 210 grain Core-Lokt bullet fits that mission cleanly. It opens on impact, holds together, and penetrates with purpose. Consequently, it makes sense for whitetail deer, hogs, and similar medium to big game.

Remington’s Core-Lokt line has earned its reputation through decades of hunting use. It does not rely on flashy design language. Instead, it gives hunters controlled expansion, useful penetration, and predictable terminal behavior. Moreover, the brass cases and Boxer primers support reloaders after firing. Retail listings confirm brass casing, Boxer primer, reloadable construction, 20-round boxes, and 10 boxes per case.

Each box contains 20 rounds. Each case includes 10 boxes, totaling 200 rounds. That case size supports sight-in, field practice, hunting season, and reserve storage.
