Remington Core-Lokt Tipped 7mm Remington Magnum Ammo 150 Grain Polymer Tip Box of 20

Last reviewed: 2026-04-18 by Jake Terry, FFL07/SOT3, NRA-certified firearms instructor.

Remington Core-Lokt Tipped 7mm Remington Magnum ammo merges the proven terminal performance of the Core-Lokt jacket with modern polymer-tip ballistics. Each 150 grain projectile exits the muzzle at 3130 feet per second, delivering 3263 foot-pounds of energy downrange. The polymer tip shifts the center of gravity rearward, flattening trajectory and extending effective hunting range beyond traditional soft-point designs. For elk, mule deer, and moose hunters working ridge-to-ridge shots, this load delivers repeatable accuracy and controlled expansion from 100 to 400 yards.

Built for the Box

Remington engineers the Core-Lokt Tipped around a match-grade polymer tip that initiates rapid expansion on impact while maintaining structural integrity during flight. The proven Core-Lokt jacket — mechanically locked to the lead core — prevents core-jacket separation even when bone is encountered. Boxer-primed brass cases permit reloading for shooters running volume ladder tests or fine-tuning seating depth. The G1 ballistic coefficient of 0.53 maintains velocity better than flat-base or exposed-lead designs in the same weight class.

Specs at a Glance

This 7mm Remington Magnum load sits in the middle of the weight spectrum — heavier than 140 grain varmint loads, lighter than 175 grain penetrators for bear. The 150 grain polymer tip delivers a flatter trajectory than 160-175 grain offerings while retaining enough sectional density for reliable penetration on shoulder shots. Hunters stepping up from .308 Winchester or .30-06 will recognize the recoil signature while appreciating the velocity advantage.

Who It’s For

Big game rifle hunters working open terrain where shots extend beyond 300 yards. Elk hunters in the Rockies who need both flat trajectory and deep penetration. Mule deer and pronghorn hunters who value wind-bucking ability and accurate first-round impacts. Shooters running controlled-feed bolt actions — Winchester Model 70, Ruger M77 Hawkeye, Mauser 98 variants — chambered in 7mm Remington Magnum. Reloaders who want quality brass cases and consistent primer pockets for load development.

At the Range

Zero at 200 yards for a maximum point-blank range of approximately 275 yards on a 6-inch vital zone, depending on rifle twist rate and environmental conditions. Expect recoil energy near 20 ft-lbs from an 8-pound rifle — manageable for extended range sessions but noticeable compared to standard cartridges. Verify zero after the first 5 rounds as magnum cartridges can shift point of impact during barrel break-in. Clean copper fouling every 40-60 rounds to maintain sub-MOA accuracy, especially with factory polymer-tipped loads that generate higher friction than monometal bullets.
