Description
7mm PRC in 170 Grain Hammer Hunter Tipped- Touted as being “a 21st Century 7mm magnum,” the PRC is based on a necked-down and shortened 300 PRC case, which in turn is a necked-down 375 Ruger. Whereas the .300 PRC requires a magnum-length action capable of handling cartridges of 3.70 inches COL (Cartridge Overall Length), the new 7mm version will fit a standard .30-06-length action (3.340 inches COL). As Ever since the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) published the specs for Hornady’s new 7mm PRC cartridge a few months back, the Internet has been buzzing with speculation. Now that the cartridge has officially launched, it’s time to quell the rumors, answer the questions, bust the myths, and provide the facts.
Much as it pains me to admit it, the 7mm PRC does just about everything better. I’ve been shooting, handloading for, and hunting with it for more than a half a year now, and I’m sold on it. Let’s take a look at just what the 7mm PRC is and does. Fundamentally, it’s a standard-length cartridge that fits into .30-06-length actions. However, the 7mm PRC’s case is not belted, so it’s bigger in diameter than the classic “Seven Mag.” and holds plenty of gunpowder.
Another critical piece to the 7mm PRC puzzle is fast-twist rifling. It’s spec’d with a rate of 1 turn every 8 inches. Enabling it to stabilize super long, aerodynamic bullets in every atmospheric condition on the planet. Recoil is zesty in light rifles without muzzle brakes, but not intolerable. With a muzzle brake or—better yet—suppressor mounted, it’s mild. Although it will never completely replace the grand old 7mm Rem. Mag., and may never overshadow the super-popular 28 Nosler, the 7mm PRC is in my opinion (and on paper) the best 7mm magnum hunting cartridge ever designed. It’s efficient. It’s ultimately compatible with the best extreme-range projectiles on the market, and as a result has unprecedented long-range reach. It’s inherently accurate—obscenely so. It pounds big-bodied game with authority. It’s the ultimate turn-key solution for performance-minded open-country hunters.
Choice Ammunition loads the 7MM PRC with the same 100% hand-loading techniques as our other calibers. Our loading techniques and extremely tight tolerances are only matched by passionate hand-loaders in their own loading rooms. Our consistencies box to box and lot to lot, are created by continuous testing at the range- adjusting varied powder and brass lot formulas to match exact velocities and points of impact as the last time we loaded this caliber. Exact seating depths and our proprietary load formulas produce a round of ammunition you can count on for accuracy and dependability each and every time- and at that critical moment in the field when it all comes down to the shot!
The Bullet:

The Hammer Hunter Tipped Bullet is a solid copper, CNC lathe-turned hunting projectile engineered for extreme precision and reliable terminal performance. Machined from a single piece of high-grade copper, it eliminates jackets and cores, delivering exceptional concentricity, uniform weight, and shot-to-shot consistency. The optimized ogive and bearing surface reduce drag and fouling while maintaining consistent pressures. A polymer tip enhances ballistic coefficient and initiates controlled expansion. On impact, the bullet sheds uniform petals while the solid shank continues forward, producing deep penetration, large wound channels, and near-100% weight retention. The Hammer Hunter delivers match-grade accuracy with dependable, ethical performance on medium to large game at a wide range of velocities.
