Looking for a case of versatile 5.56x45 ammo? Winchester’s M855 ammunition will serve you like a champ at the shooting range, but its penetrator bullets are also poised to help you defend your castle!
This round’s 62 grain bullet looks just like any other FMJ on the outside, but with one exception: Its tip is painted green. That’s the sign that its lead core contains a seven-grain steel penetrator tip, which enables the bullet to reliably pierce sheet metal and other durable barriers at close-to-medium range.
This is magnetic ammo! Many ranges won’t let you bring it on their premises, as a bullet which contains steel poses a higher risk of damaging range equipment. The heavier 62 grain bullet is most accurate when fired from a 1:9” or 1:8” twist barrel, but if your AR-15’s barrel has a 1:7” twist then you’ll still enjoy firing this ammo.
This American-made ammo is loaded with new production brass cases. You can see where they were heat-treated at the factory, because Winchester didn’t spend time polishing the cases afterward. This Boxer-primed ammo is great for handloading too!

Bought this ammo over a year ago. Went straight into the ammo can. Finally shot about 500 rounds the other day and the accuracy at at 400 yards was what you’d want. The main thing I liked was not a single misfire. This is what i used to carry in my rifle while deployed over seas. I would give it three thumbs up but the lord only gave me two thumbs (Posted on 5/16/2025)

The furthest range around is 400m, was able to get consistent hits on steel even with a red dot. At 25m and 100m pretty consistently at 1.25MOA. On a 13.7 barrel the ballistics were a bit different compared to M855A1, with noticeably less bullet drop at 300m and 400m. (Posted on 2/27/2024)

Great ammo. Just wanted to make a general observation about M855. If the M855 like this brand doesn't have the NATO stamp (circle with a cross on the bottom), then you MAY have to rezero your rifle? Nothing wrong with other brands that don't have NATO stamp, they MAY be just packed to slightly different tolerances? (Posted on 3/17/2022)
