Hi All:
Firing a RRA NM, I can regularly shoot 1 MOA with even PMC 55 grain ammo. So this last weekend, I ran out some XM 855 at 100 yards and it looked like I was throwing rocks. It was off so much that at first I thought perhaps my scope mount had shaken loose. No, it was fine. I immediately stopped shooting this stuff and ran out two five round targets using 69 grain Fiocchi Match ammo. Both targets immediately were sub MOA. So today I went back to the range to test several different brands and compare the results. Short story, the XM855 was incredibly inconsistent target to target. In some cases maybe a 2 MOA group, and in others, well, no sense in even calling it a group. Now the interesting part was that one of our Camp Perry type shooters told me that he had heard there was a common problem in consistently seating the steel core in the jacket, resulting in very inconsistent performance round to round. The explanation sure makes sense and explains a lot.. Has anyone else heard of this? |
| XM855 isnt exactly "match" stuff. I am sure there will be plenty along to repeat the same thing. Factory 855, if i get 2-3 MOA i consider myself lucky. My reloaded ss109 (same difference) I am happy if i can even get moa out of it. That being said, for what it is, I have a few K of these rounds made up. I have my 77 SMK's if i want "match" quality. |
| 3" with M855 is good. I built a 16" 1:7 middy for shooting 75-77gr and it shoots to at least half that. My other AR is a Colt 6721 with 1:9, and I have a case of hand-made 62 gr 'SS109' that shoots very tight in that one. I don't use much of it because the old guy that made it is not able to reload now. He had a huge rep as an ammo maker for many years. This ammo has IMI bullets and is made on once-fired Lake-City brass. He was a perfectionist and it shows in this ammo. I actually sold some M855 issue ammo last year that I had been accumulating for years, not realizing the inherent inaccuracy of it. I still have plenty, because its still a good 'business' round, but it is simply not the quality I'm now looking for since I have switched to all-optical sights. I mean, it stinks when you get a nice scope and still shoot 3", and M855 still isn't what I would call 'cheap'. The PRVI M855 shoots better, and in the other rifle I use PRVI 75 gr. |

XM855 out of a rack grade gun is specced to produce 4MOA. So 2MOA from a precision gun seems about the correct expected performance. I don't get why people find this so hard to understand. Agreed. That said, its same as any other ammo, different barrels like different things. My 6940 seems to sling it remarkably well, at least the couple hundred rounds i have put through it. |

Because most who buy it , never shoot it at a target at 100 yds for accuracy . My friends blast away at dirt piles at 10 yds or just hoard it. 
I will admit for prepper types , it is very desirable as a barter ammo. Second only to .22LR. |

For what it is worth I don't expect much in the way of accuracy from either XM193 or XM855. It isn't exactly intended to be precision ammo and I don't know why people expect it to be. |

I am gett9ng 1.5 inch groups from IMI M855 out of a 1-9 Bushmaster, hardly a precision rifle. 3 X ACOG no less. Have been doing this well for years. I have early production SS109 from FN HErstal, same thing. Ditto, early LC M855. I dont know when the spec for M855 went South but it certainly has.
If you want some accurate M855 try PMC X-Tac. Not quite as fast as LC but consistantly accurate. Almost as good as IMI. |

I too was surprised by this ammo's accuracy in comparison to LC, AMA DENEX and ADI (Aussie) M855. |

As others have noted, not all M855 is the same. I have some Federal Lake City M855 headstamped LC12 that is shooting 1.2 MOA from a 16" melonite 1:9 barrel with consistency. I bought a 500 round bulk box and have been pleasantly surprised.
It is worth trying different brands. Now that the ammo is being produced for civillian consumption, perhaps Federal's production standards are better. This is pretty good for cheap ammo not intended to me match grade. |
