Remington Ammunition 28987 Core-Lokt 7mmBC 175gr 20 Per Box/10 Case

The Remington Core-Lokt 7mmBC ammunition in 175-grain loads represents seven decades of proven big-game hunting performance. This is working ammunition for hunters who prioritize reliability and field-tested results over novelty—a controlled-expansion centerfire rifle round that has earned its reputation through consistent takedowns across North America and beyond. Whether you're hunting elk in the high country or taking longer shots at distance game, the 7mmBC in this 175gr configuration delivers the predictable terminal performance that Core-Lokt has become known for.

At the heart of Core-Lokt's enduring appeal is its straightforward design: a tapered copper jacket mechanically locked to a solid lead core. When this projectile meets game, that construction produces controlled expansion—roughly double its original diameter—while retaining enough mass to drive deep. There's no marketing mystique here, just a bullet that does what hunters expect it to do, shot after shot. With a ballistic coefficient of .429, these 175-grain soft points will carry energy downrange better than lighter loads in the same caliber, making them suitable for the longer-range work that modern hunting often demands.

Remington loads this ammunition to a 3,100 fps muzzle velocity, a moderate, repeatable standard that balances power with barrel life and shooter recoil management. You'll receive 20 rounds per box—enough to work up a load or establish a hunting zero—with the option to purchase by the case for volume hunters and serious shooters who want consistency across multiple range sessions and seasons.

Frequently Asked Questions

What is the 7mmBC caliber and what game is it designed for?

The 7mm Backcountry is a centerfire rifle caliber engineered for big-game hunting. Remington's Core-Lokt load in 175 grains is intended for hunting large game species, particularly at longer ranges where the ballistic coefficient of .429 helps retain downrange energy.

What makes Core-Lokt bullets expand reliably?

Core-Lokt uses a tapered copper jacket mechanically locked to a solid lead core. Upon impact, this design produces controlled expansion—approximately doubling the bullet's diameter—while retaining weight for deep penetration. This two-part expansion is a hallmark of the design's field-proven performance.

Is this ammunition suitable for long-range hunting?

Yes. The 175-grain 7mmBC load carries a ballistic coefficient of .429 and a 3,100 fps muzzle velocity, both of which support extended-range applications. The supplier description specifically lists this ammunition under "Long Range" usage, making it suitable for hunters who engage game at distance.

What do I get in a box, and how are cases packaged?

Each box contains 20 rounds. Cases are packaged with 10 boxes per case, allowing bulk buyers to stock consistent ammunition for extended hunting seasons or range work.
