Details

If you own an AR-15, then you can never have an overabundance of 5.56x45 ammunition. This case of M193 spec ammo is all you need at indoor and outdoor rifle ranges, and if your AR ever becomes your ticket out of a life or death situation, there’s no way you’ll wish you had less of Winchester’s ball ammo!

This cartridge features the semi-auto’s quintessential FMJ bullet. It’s comprised of a solid lead core and hard gilding metal jacket, so there’s no steel in there to get it barred from use at indoor ranges. At 55 grains the round’s 3,180 fps muzzle velocity is just about average as can be, with a 0.250 G1 ballistic coefficient that yields a level trajectory. There’s no expansion-promoting features to an FMJ, although the cannelure circling its shank will help prevent the bullet from creeping back or forth in its case before it is fired.

This cartridge’s case is made of brass and fresh from the factory. People ask all the time if the gray on this ammo’s cases means they are reloaded, but that’s a totally normal marking for military-grade brass. It just means it has been annealed, a process which fortifies brass and makes it able to more reliably return to its original dimensions after ignition. Winchester loads consistent and non-corrosive primers for reliable, clean ignition.
