Howdy Folks,
New member here, and I have a noob question I'm hoping someone can help me with. I have searched the forums, and cannot find this info. What are the differences in the 62gr ammo variations with the following designations: XM855, XM855F, XM855LC, XM855LC AC1, XM855LC AC2, and the other 855 designations I have left out? I know that one of them is lead core with a steel tip, and one is a steel core. Which are which? Thanks much for the help. |

From Federal / American Eagle / Lake City? I'm fairly sure the only difference is in the packaging, e.g. "box of 20", "box of 30 on stripper clips", "bulk 1,000 rounds in a bag", etc. There may be QC differences, but ostensibly they're all the same round. ^^^ Correct, just a difference in packaging. |

OK thanks. So is there a designation that differentiates the lead core w/steel tip round from the all-steel core round? I am trying to avoid the all-steel core rounds. M855A1 I have seen a cross-section cut photo (I think from a link somewhere on this site) of the M855 that has a lead core, and a steel tip over the lead core. Am I understanding correctly that there is also an M855 variant whose core is all steel? Is this M855A1 the all-steel ? |

Thanks much Region
I've always been a pistol guy, The Job, competitions, etc, but a few years ago my dept put together a comprehensive carbine course, Ibought my first carbine, and came to realize a pistol is what you use so you can get to your rifle. After a few years of shooting and carrying, I've learned a bit, but it is surprising how little some of our instructors know about specifics and details of the m4 carbine, especially on a dept our size. I have learned quite a bit from this forum, although it has been as a "lurker" Thanks to everyone for all the great info, I will continue to pass it on to my coworkers. |

This is the second time I'm posting this this morning: I hope the people in charge of coming up with the stupid naming convention at Federal/ATK get a severe case of crotch-rot for the idiocy they're forcing us to deal with. I here ya, Fed is just goofed up on the ammo naming. |

Yep, I agree, confusing as all hells. I've always bought the cheapest 55gr lake city for range training, and our dept. issues us Hornady TAP. Only recently have i started looking at the M855 stuff, because I just don't trust TAP penetration through a barrier like vehicle glass. Awfully confusing, with all of federal's numbers, letters, symbols and heiroglyphics. And I'm still confused on the whole M855 tungsten core issue, etc etc. Glad I found out from you guys that wikipedia is often wrong. |

The XM855... you buy from Federal, has a steel penetrator, lead core and a copper jacket. The NEW US Army M855A1 has either a steel or tungsten penetrator tip and no lead(you probably will not see any of this on the commercial market for some time if at all) A couple of years ago, there was an experimental round that had all copper plus a tungsten powder/nylon penetrator inside, this is what I assume is at SG ammo listed as XM855LFB . Supposedly the tungsten powder got into the water table and it is toxic so it failed as an experimental round. |
