It’s not lead-free. It’s not match-grade. It’s not blessed by monks during a full moon. It’s Winchester’s tried-and-true USA series 5.56x45 ammunition – precisely the ticket for all your high-volume mag-dumping target shooting needs!

This cartridge is loaded to M193 specifications, which only means it’s loaded to the most basic specifications. That’s a 55 grain full metal jacket projectile, which assures smooth feeding and consistent accuracy. The solid point bullet isn’t designed for terminal expansion, although its steel-free copper-alloy jacket does make it a sure bet for blasting bullseyes at ranges which require nonmagnetic ammunition.

Winchester’s Boxer primers and propellant are both formulated to minimize fouling of the action and barrel. Their brass cases are absolutely brand new and reloadable, so make sure to pocket those empties! (The grayish necks are the normal result of the annealing process which strengthens brass. They will not negatively impact any aspect of performance.)

A: Thanks for reaching out Buck! Winchester recently confirmed to me that they require the individual UPC codes for each box inside the case of ammo in order to pay the rebate.
