5.56X45 WINCHESTER USA 62 GRAIN FMJ M855 (1000 ROUNDS)

You don’t want just any 5.56x45 M855 ammunition. You want ammo that is backed by generations of excellence – precisely what Winchester instills into each and every box!

Here’s some true military grade materiel for your plinking and target shooting pleasure. Each round is loaded with a carefully standardized 62 grain full metal jacket projectile – but it isn’t just any FMJ. The “penetrator” bullet features a partial steel core which enables it to pierce sheet metal several hundred yards downrange, as well as split into two separate pieces following collision with a soft medium.

A barrel with a 1:6” or 1:7” rate of twist is adequate for M855 ammo, but the best accuracy can only come from a 1:8”, 1:9” or 1:10” twist. More importantly, this ammo’s ability to attract a magnet makes it most unwelcome at many indoor ranges. Be sure to call ahead and ask if M855 is OK before investing in an entire case.

Winchester’s brass cases cycle fluidly and offer great value to handloaders. Their propellant minimizes fouling, and their Boxer primers are most certainly not corrosive. Order a case today and you’ll get something even better than ammo. You’ll get ammo … with free shipping!
