The Remington Core-Lokt 7mm Remington Short Action Ultra Magnum 150-grain Pointed Soft Point (PSP) Brass 20-round box is a high-performance centerfire rifle cartridge engineered specifically for big game hunting where flat trajectories, controlled expansion, and deep penetration are required at extended distances. A common friction point with high-velocity short-action magnum loads is premature bullet fragmentation or jacket-core separation upon target contact, which drastically reduces retained weight and limits penetration depth. Remington completely resolves this issue through its mechanically locked jacket-to-core design, which maintains structural integrity during high-speed impact.
The core technical advantage relies on controlled expansion dynamics under magnum velocity. The Pointed Soft Point (PSP) nose profile initiates rapid deformation upon contact, while the mechanically locked, progressively tapered copper jacket regulates the expansion rate to approximately double the bullet's original diameter without fragmenting. Featuring a 0.346 G1 ballistic coefficient, the aerodynamic bullet cuts through air resistance, preserving downrange momentum and ensuring linear penetration through dense tissue and heavy bone beyond 300 yards.
Launching its 150-grain Core-Lokt PSP projectile at a blistering muzzle velocity of 3,110 FPS, this 7mm SAUM load generates an impressive 3,221 ft-lbs of muzzle energy while maximizing short-action cycling efficiency. Assembled in precision-drawn, reloadable virgin brass cases fitted with reliable Boxer primers and clean-burning propellants, it delivers uniform chamber pressure curves, dependable ignition, and smooth extraction across bolt-action rifles. It is a proven choice for whitetail deer, mule deer, elk, and open-country big game hunting.
