Winchester 5.56MM 62 GR FMJ M855 PENETRATOR

Most accurate 5.56 I have found
When I got my M4 Carbine, I got a bunch of generic 55-grain .223 ammo. It was “OK” but not great. Then I got this 77-grain 5.56 that uses Sierra Match King bullets. With this, at 50 yards I got two doubles in 5 shots. If I had a scope, I believe it would have made one small ragged hole for all five shots. Now my only weakness is my old eyes.

Having fun shooting with son’s 👍

Great ammunition. Zero failure to fire in 250 rounds. Will buy again. Let’s go Brandon

I chronographed this ammo at 2525fps (74F, 60%RH, el 1102′) out of a 16″ FN tatical ii. Ballistics were accurate out to at least 840yards with that velocity and G1.

I ORDERED ONE BOX ABOUT WHEN YOU ASKED YOUR QUESTION JUST TO TRY IN MY MK12. I HAD NO PROBLEMS, SHOT CLEAN AND TRUE. MY LOT # IS 00265/B HOPE THAT THIS HELPS… HAPPY SHOOTING

super accurate in all my ARs and SBRs with 1:7″ twist rates, it is expensive but worth every penny for maximum accuracy and performance.

This would only be good self defense ammo if you don’t have to worry about over penetration. This ammo being on the heavier side would pass through an intruder and keep going. Not ideal if your have family members in different rooms throughout your house.

I’ve received two separate lots of this ammo ordered at different times. The first was 00225/G which grouped 2.052in at 300yrd out of my Ruger EPR 5.56. It ran just fine with no miss-fires. The next lot, the one I now have 1500 of, was 00276/G which in an entirely different story.

These rounds have a military crimp on them so if you’re going to reuse them to reload with you’re going to have to take the military crimp out of it
