20rds – 5.56x45 Winchester 62gr. FMJ M855 Ammo Details

Some call it the M855. To others it is known as the SS109. But we like to call it the penetrator, because that perfectly sums up what this 5.56x45 cartridge’s bullet is designed to do!

If not for the green paint on its tip, this round’s bullet would be no different from any other FMJ. Its hard copper jacket promotes reliable feeding and prevents barrel leading. But it weighs 62 grains instead of 55 because it has an extra seven ounces of steel in its tip. That’s to help the bullet to pierce steel plating, which it reliably does up to around 650 yards. The penetrator bullet can also tunnel up to 20” into soft flesh, and it has a good chance of fragmenting to track to separate wound channels as it does so.

Winchester loads this ammo with clean burning propellant and non-corrosive primers to preserve accuracy and reduce fouling. They also give it new production brass cases. The smoky discoloration around its shoulder doesn’t indicate that these cases have been reloaded – rather, it shows they’ve been properly heat-treated so they can expand inside the chamber and then be reloaded several times.
