Description
When Remington introduced Core-Lokt ammunition in 1939, they set a standard that still holds today. This new Tipped version takes that heritage and adds what modern hunters need: flatter trajectories, better ballistic coefficients, and consistent downrange energy. The 140-grain projectile in .280 Remington caliber splits the difference between velocity and manageable recoil, making it a solid all-around choice for medium to large game.
The green polymer tip does the real work here. It shields the bullet's point from magazine wear that can hurt accuracy, improves the aerodynamic profile for better wind-bucking performance, and gets things rolling on rapid expansion when the bullet contacts game. The Core-Lokt jacket itself remains unchanged from what's proven itself thousands of times over—a mechanically locked design that controls expansion while keeping weight retention high for deep penetration. The result is a controlled mushroom that expands quickly without fragmenting.
The .280 Remington's Practical Range
With a 3020 fps muzzle velocity, these rounds stay effective well beyond typical hunting distances. The 140-grain bullet has enough sectional density to carry energy through heavy cover, and the improved ballistic coefficient means less bullet drop and wind drift at extended range than older Core-Lokt loads. The cartridge itself sits nicely between lighter recoil-conscious loads and heavy magnum rounds—powerful enough for serious hunting without excessive shoulder punishment.
Why Brass Casings Matter
You get polished brass that cycles smoothly in bolt-action or semi-auto rifles. That consistent feeding means more reliable ignition and better shot-to-shot consistency. Plus, the brass is reloadable, so if you're into handloading, these give you quality components to work with after the factory rounds are gone.
Twenty rounds per box is the standard for hunting ammunition—enough to practice with, sight in your rifle, and carry a reasonable supply into the field.

Frequently Asked Questions
What's the difference between Core-Lokt Tipped and standard Core-Lokt rounds?
The polymer tip improves the bullet's aerodynamic shape, which increases its ballistic coefficient for flatter trajectories and better wind resistance. On impact, the tip initiates expansion while the Core-Lokt jacket controls how the bullet mushrooms. The tipped version essentially gives you modern ballistic performance while keeping the proven Core-Lokt terminal performance that hunters have relied on since 1939.
What kind of game is this .280 Rem 140gr load best suited for?
The 140-grain bullet works great for deer-sized game and medium-sized animals like antelope. It's capable on elk when you're inside 300-400 yards with good shot placement. The .280 cartridge is versatile enough that this load is practical for most big-game hunting in North America when you're not specifically chasing the largest animals.
Can I reload these brass cases?
Yes. Remington provides polished brass casings that can be reloaded multiple times. You get quality components to work with, which is valuable if you handload. Just treat the brass like any other reloadable brass—inspect it, clean it, and follow standard handloading practices.
How does this ammunition cycle in semi-auto rifles?
The polished brass casings are designed for smooth feeding in both bolt-action and semi-auto hunting rifles. The consistency of Remington's loaded ammunition means reliable chambering and extraction. That said, individual rifle reliability varies, so it's always a good idea to test any new ammo load in your specific rifle before hunting season.
