Frequently Asked Questions
Is the 100-grain .243 Win Core-Lokt suitable for deer hunting?
Absolutely. The 100-grain PSP is widely considered the ideal bullet weight for hunting whitetail deer, mule deer, and pronghorn with a .243 Winchester. It offers superior penetration and energy retention compared to lighter .243 loads, and the Core-Lokt's controlled expansion ensures reliable terminal performance even at longer hunting distances. Many experienced hunters prefer this weight specifically because it minimizes meat damage while still delivering clean, ethical kills.
How does the Core-Lokt PSP differ from a standard soft point bullet?
The Core-Lokt Pointed Soft Point (PSP) features a tapered copper jacket that is mechanically bonded — or "locked" — to the lead core. This design controls expansion to approximately 2X the bullet's original diameter while maintaining high weight retention, preventing the bullet from fragmenting or shedding its core prematurely. The pointed nose profile also improves the ballistic coefficient compared to a round-nose soft point, giving you a flatter trajectory and more retained velocity at distance.
Will this ammunition cycle reliably in semi-automatic .243 rifles?
Yes, Remington Core-Lokt ammunition is loaded to standard SAAMI pressure specifications and is designed to function reliably in bolt-action, lever-action, and semi-automatic rifles chambered in .243 Winchester. As with any ammunition, it's always a good practice to verify compatibility with your specific firearm's manual and to test for reliable feeding before heading into the field.
