Winchester 5.56x45 M855 ammunition is perfect for all your everyday AR-15 target shooting and plinking needs. Importantly, this ammo’s bullets will attract a magnet – but not because they have economical bimetal jackets.

This round’s 62 grain FMJ has a green-painted tip to indicate that its core contains a penetrator tip. This seven-grain steel cone helps the M855 bullet to pierce metal plating and other barriers much more effectively, and its slightly higher weight increases its sectional density so that it can penetrate soft tissue more efficiently.

This ammo is loaded at the U.S. government’s Lake City Army Ammunition Plant with non-corrosive Boxer primers, clean-burning powder and new production brass cases. The gray around the case mouths is the natural byproduct of the annealing process which strengthens brass!

Use a 1:9 or 1:8 twist barrel for the best accuracy; a 1:7 twist is also serviceable.

Q: Is this considered a "NATO round" thus I can use in my S&W M&P15 safely?

Posted On: 6/20/2022 By: Ed Parker

A: Thanks for reaching out Ed! The full and official name of this cartridge is "5.56x45mm NATO." When you see ammo called 5.56x45mm, 5.56x45 or just 5.56, it's all the same thing as 5.56x45mm NATO. Your M&P15 is specifically designed to fire this ammo. Just take care that the M855 spec cartridge's bullet contains steel, as many commercial ranges prohibit bullets that can attract a magnet.

Q: Is this ammo legal in NJ?

Posted On: 4/23/2022 By: Daniel Zalink

A: Thanks for reaching out Daniel! I am not qualified to give legal advice, and you should not interpret anything I say as legal advice. That said, it is my understanding that M855 ammunition is indeed legal in the state of New Jersey. Just take care before you order it, because many commercial ranges prohibit bullets which can attract a magnet.
