MK262 Mod1 for distance, 62gr SOST for general purpose. There is ammo that is not available or used by conventional and general special operations personnel that is extremely effective from 0-500+ meters.

M855A1 is acceptable in tissue, but like M855 (Greentip) is extremely inaccurate

It was not unusual to get lots of M855 that grouped 8+ inches for 10 rounds at 100 yards. Early lots of M855A1 were better at around 3.5 MOA, however they are getting worse and the last few I have shot were 4.5 to 5 MOA from match barreled guns, and 6+ from M4’s. Combine 5-6 MOA groups with an non-free floated barrel, and you aren’t reliably hitting vitals past about 100 from good positions. Throw a VFG on the rail and use it, or rest on the hood of a truck, or use a a barricade and you’ll get 12-18 MOA shifts in point of impact. That’s all provided you actually got a real zero. The way the Army, Navy, and Airforce zero, and to a slightly lessor extent the Marines ensures that you aren’t going to reliably hit anything between 75-300 anyways. Then combine the current general issue optics (Acoq)..... it goes downhill from there.


In contrast a properly setup M4 (SOCOM Block II, URG-I, etc) with MK262 zeroed correctly will keep it’s rounds in the vitals out to 450-500 yards mechanically.



Formidilosus,

Thank you, I greatly appreciate you sharing your experience with us.

I had not idea the quality control on our M855 variants had deteriorated to such a degree. I find it pretty pathetic that we send our solders into harms way with such garbage ammo, when it doesn't need to be. I have some Winchester white box M855 I'm still shooting that was surplussed by the Denver Police Department in the late 90's. Out of a match barrel it's consistently 1.5"-2" ammo at 100 yards. The recent lot of the IMI equivalent I picked up from Midway gives similar performance. It's really unacceptable that we, as civilians seem to get better quality control from Midway than what's issued to our troops when American and Allied lives are on the line.

I'm glad to hear you have some good options. Let's just hope the QC on those doesn't go into the pisser as well.

Thanks again.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
