Remington Core-Lokt 7mm Rem Mag 140gr 20 rounds is a box of 140-grain pointed soft point core-lokt big game ammunition (Remington part no. 28821). Remington has built Core-Lokt around a controlled-expansion design since 1939, locking the jacket and lead core together so the bullet opens reliably and keeps its weight. Remington publishes a muzzle velocity of 3175 fps and 3133 foot-pounds of muzzle energy for this 7mm Rem Mag load, with 2458 fps still on the clock at 300 yards. Remington lists its use as big game, long range, which suits a hunter who wants a proven bullet design rather than a specialty load. This 7mm Rem Mag 140-grain version is distinct from the other Core-Lokt calibers and weights, so match both the chambering and the bullet weight to your rifle before you order.
