Description
The Remington Core-Lokt .260 Remington 140-grain ammunition brings decades of proven hunting performance to one of the most versatile mid-range cartridges. This load runs at 2750 fps with 2351 ft-lbs of muzzle energy, delivering the kind of flat trajectory and hard-hitting power that makes the .260 a go-to choice for hunters who want something between a .243 and a .308.
What Makes the Core-Lokt Design Work
The tapered copper jacket is mechanically locked to a solid lead core, a design detail that prevents jacket and core separation on impact. Instead of coming apart, the bullet expands in a controlled manner and retains the majority of its weight. That weight retention is what separates Core-Lokt from cheaper ammo options and why it's been the preferred choice of serious hunters for over 80 years.
.260 Remington 140-Grain Performance
At this grain weight, the .260 finds its sweet spot. The pointed soft point profile helps it cut through air efficiently, maintaining velocity downrange without the recoil punishment of a .300 magnum. Whether you're hunting whitetail out to 250 yards or taking pronghorn in open country, the 140-grain Core-Lokt gives you the penetration and expansion you need without excess. The ballistic coefficient of 0.435 keeps the round moving downrange with minimal wind drift.

Frequently Asked Questions
What game is the .260 Remington 140-grain Core-Lokt suitable for?
The 140-grain Core-Lokt is excellent for medium-sized game including whitetail deer, mule deer, pronghorn, and similar species. The 2750 fps velocity and controlled expansion design work well out to typical hunting ranges. While capable of taking larger game, it's optimized for medium-sized animals where the penetration and expansion balance of this load shine.
How does the Core-Lokt bullet design compare to other hunting rounds?
The Core-Lokt was the original controlled-expansion hunting bullet, introduced in 1939. Its mechanically locked jacket and core prevent separation on impact, ensuring consistent weight retention and penetration. This design has been proven on countless hunts across continents and remains one of the most reliable terminal performance designs available in factory ammunition.
Is this ammunition reloadable?
Yes, the .260 Remington Core-Lokt uses reloadable brass cases with Boxer primers, so once fired, the cases can be reloaded. This makes it a good choice for shooters who reload and want to develop custom loads while still getting proven factory ammunition for immediate use.
What's the advantage of the pointed soft point profile?
The pointed design improves aerodynamics and ballistic coefficient compared to round-nose bullets, which means the 140-grain bullet retains velocity better downrange. This translates to a flatter trajectory and better energy at distance, making shot placement more forgiving at extended ranges while still delivering the consistent expansion Core-Lokt is known for.
