Description
The Remington High Performance .243 Winchester 80-grain load delivers what you expect from a Core-Lokt bullet: controlled expansion, solid weight retention, and the kind of terminal performance that's made this design a favorite for generations. This is the ammunition that works when it matters.
What Makes the 80gr Core Lokt Work
The .243 Winchester is all about versatility, and this load leans into what the cartridge does best. At 3,350 feet per second, you're getting a flat shooting trajectory that makes field adjustments minimal out to practical hunting ranges. The muzzle energy clocks 1,993 foot-pounds, enough authority to put deer-sized game down cleanly when you do your part with shot placement. The 80-grain bullet weight strikes the right balance between velocity and penetration for medium game without excess recoil that fatigues you during a long hunting season.
Core-Lokt Bullet Design and Performance
What separates Core-Lokt from run-of-the-mill hunting ammunition is the mechanically locked jacket and core. The copper jacket tapers progressively thinner toward the nose and thicker at the heel, which creates controlled expansion rather than explosive fragmentation. When the bullet impacts, it expands reliably while the locked core stays together, delivering the kind of weight retention that means deeper penetration and more decisive results. You get rapid expansion plus penetration that matters, especially in the .243 where energy drops as distance increases.
Good for What You Hunt
This ammunition is built for hunting whitetail, mule deer, and similar-sized game animals. It's particularly effective from close range out to around 300 yards where the .243 maintains its sweet spot of velocity and energy. The pointed soft point configuration adds a touch of aerodynamic efficiency without sacrificing the reliable expansion that Core-Lokt is known for. The brass cases are reloadable, so if you're into handloading, your investment extends beyond a single use.
Remington High Performance ammunition has been a standard in hunting camps for good reason. The combination of tight tolerances, premium components, and the proven Core-Lokt design means you get consistency box after box without guessing whether your ammunition will perform when the moment counts.

Frequently Asked Questions
What game is this .243 Winchester load designed for?
The 80-grain Core-Lokt is built for deer and similar-sized medium game. The combination of velocity and controlled expansion makes it effective from close range out to about 300 yards. While you can use it on larger game, the 80-grain bullet is optimized for the deer-sized range where the .243 Winchester truly excels.
Can I reload these brass cases?
Yes. These come in reloadable brass cases, which means you can reload them after you fire them. Many hunters appreciate this, as it extends the value of your ammunition and lets you customize loads if you're into handloading.
How does the Core-Lokt bullet perform on impact?
The Core-Lokt design uses a mechanically locked jacket and core to prevent separation on impact. This delivers controlled expansion with good weight retention, creating a larger wound channel while the bullet penetrates deep enough to reach vital organs. The tapered jacket helps the bullet expand at a measured rate rather than fragmenting, which is what makes this design reliable across a range of impact velocities.
How far can I effectively hunt with this ammunition?
The practical maximum for medium-sized game is around 300 yards. At this distance, the .243 Winchester still carries enough energy (roughly 1,000 foot-pounds) to be effective. Beyond 300 yards, energy drops off quickly with the 80-grain bullet, so accurate shot placement becomes even more critical if you decide to stretch the distance.
