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

Remington’s Core-Lokt has filled tags for generations, and now it is available for the 400 Legend, one of the newest straight-wall deer cartridges. This listing is Remington Core-Lokt 400 Legend 210 grain soft point ammo, MPN R21307, sold as 200 rounds. It is a familiar bullet design paired with a modern cartridge for hunters in straight-wall zones.

This load is rated at 2,250 fps. The Core-Lokt bullet uses a jacket that is mechanically locked to the lead core, which controls expansion and helps the bullet stay together for penetration on deer and hogs. At 210 grains, it is a heavy, wide bullet that carries a lot of momentum at the moderate distances where straight-wall cartridges are typically used. It is a hunting bullet first, but its price makes it reasonable to practice with as well.

This ammunition fits rifles chambered in 400 Legend, including the Winchester XPR and AR-15 rifles fitted with a 400 Legend barrel, bolt, and magazines. A common question is how far the 400 Legend is effective on deer. Most hunters keep shots within about 200 yards, where the heavy bullet still has good energy and the drop is manageable. Another common question is whether you can use 400 Legend in an AR-15 with your existing parts. You need a 400 Legend barrel and the correct bolt and magazines, so check with the upper’s maker before mixing parts.

Remington R21307 is new production ammunition, not reloads, made in the USA. It uses boxer-primed brass cases with non-corrosive priming. This listing ships as 10 boxes of 20 rounds for 200 rounds total from one lot. That lets you zero and practice with the exact cartridge you plan to carry into the woods, and keeps the same lot on hand for the seasons ahead. Shooting from a rest at 100 yards, then checking holds at 150 and 200, will tell you everything you need for a typical deer stand.
