The Winchester Super X 223 Remington 64 grain Power-Point JSP delivers medium-game hunting performance from AR-15 and bolt-action platforms. A 223 Remington round is a centerfire cartridge originally developed for military use, later adapted for civilian hunting and varmint applications. This load pushes a 64 grain jacketed soft point bullet to 3020 feet per second at the muzzle, generating 1296 foot-pounds of energy — placing it in the upper range for 223 hunting loads targeting coyote, feral hog, and deer-sized game at moderate ranges.

Performance at a Glance

Winchester engineers the Power-Point bullet with strategic notches around the jacket mouth. On impact, these notches initiate controlled expansion — the lead core mushrooms while the copper jacket peels back in uniform petals. This design transfers energy into tissue rather than over-penetrating, a critical feature when hunting in mixed terrain or near property boundaries. The 64 grain weight sits between lightweight varmint loads and heavier barrier-blind offerings, balancing velocity retention and terminal effect. Sectional density of 0.182 and a G1 ballistic coefficient of 0.251 provide adequate stability and wind resistance inside 200 yards, the practical effective range for this cartridge on medium game.

Brass case construction and non-corrosive Boxer primers allow component recovery for reloaders tracking lot performance or tailoring loads to specific barrels. Each case weighs 0.585 pounds per 20-round box, classified as DOT-regulated for shipping. Store in a cool, dry location away from ignition sources.
