1000 Rounds of 55gr FMJ 5.56x45 Ammo by Winchester

Your world is about to change … permanently. And for the better! Now that you’ve discovered Winchester’s behemoth 1,000-round case of 5.56x45 ammunition – divided into just two convenient 500-round boxes – you’ll be able to shoot targets morning, noon and night without having to worry about dreaded empty magazines.

This round earns its M193 specification courtesy of its 55 grain full metal jacket bullet and 3,180 fps muzzle velocity (out of a 20” test barrel). It’s an unsophisticated yet reliable little piece of hardware: totally devoid of any steel that could have moved a magnet, with a hard copper-alloy shell that ensures smooth feeding and cleaner overall performance. There’s even a little cannelure to prevent recoil from knocking the bullet loose from its purchase in the case mouth!

Once you’ve put dimples in this ammo’s noncorrosive Boxer primers, you’ll still have high-quality military-grade brass cases for your upcoming handloading projects. Don’t fret about the cases’ cosmetic discoloration. That’s the normal byproduct of the annealing process, and only proves that they were made correctly!
