Description
The Remington Core-Lokt .30-06 Springfield 180-grain soft point is about as straightforward as hunting ammunition gets. Since 1939, this round has done one job better than just about anything else—it puts game down effectively and consistently. The tapered copper jacket locks to a solid lead core, and when that bullet hits game, it expands in a controlled mushroom shape while keeping its weight for penetration. At 2700 fps with 2913 ft-lbs of energy, the 180-grain loading hits that sweet spot for everything from whitetail to elk across typical hunting ranges.
The Core-Lokt Design Works Because It's Simple
The genius of the Core-Lokt is in controlled expansion. Instead of a bullet that either pencils through or fragments apart, this design expands to roughly twice its original diameter while retaining around 75-80% of its weight. That combination creates a larger wound channel and ensures deep penetration through heavy muscle and bone. The tapered jacket accomplishes this by being thin at the tip for initiation and progressively thicker toward the base, keeping the core locked in place as the bullet deforms.
Built for Real Hunting Scenarios
These rounds use non-corrosive boxer primers and reloadable brass cases—meaning you can shoot them and reload them later without any corrosion issues. Each box contains 20 rounds, so you get a manageable quantity without breaking the bank. The 180-grain weight is the classic choice for the .30-06; it balances velocity, energy, and trajectory for most North American hunting situations. Whether you're hunting in timber, open country, or anywhere in between, this load performs at distances from close encounters to reasonable hunting ranges.
Core-Lokt ammunition doesn't need a sales pitch because it's been proving itself for nearly nine decades. The track record speaks for itself.

Frequently Asked Questions
What game is the 180-grain Core-Lokt designed for?
The 180-grain Core-Lokt is an excellent choice for elk, deer, moose, and bear. This weight sits right in the middle for the .30-06 platform and provides the energy and penetration needed for medium to larger frame game across typical hunting distances. It's considered the ideal all-around weight for North American big game.
How does the Core-Lokt bullet expand on impact?
The tapered copper jacket is mechanically locked to the lead core. When the bullet impacts game, the thin tip initiates expansion while the thicker jacket base holds the core in place. This controlled design creates a mushroom-shaped expanded bullet that retains most of its original weight while still creating a substantial wound cavity for effective energy transfer.
Can these cases be reloaded?
Yes, these rounds use brass cases with boxer primers, so they can be reloaded. The cases are non-corrosive, meaning there won't be any residue buildup that damages equipment or makes reloading difficult. Just inspect cases before reloading as you would with any ammunition.
Is the 180-grain load suitable for long-range hunting?
The Core-Lokt soft point shoots flat enough for typical hunting ranges but isn't optimized for extended-distance shooting. The ballistic coefficient of .383 is respectable for a traditional soft point, but if you're regularly taking shots beyond 300 yards in open country, the newer polymer-tipped Core-Lokt Tipped variant offers better downrange performance.
