A few years back I pick up some IMI 62gr steel core SS109 bullets for reloading. I loaded them up (just in case) & labeled my ammo can SS109. Now I'm seeing M855 being sold by Ammoman & Adco. What's the difference & why the two different number designations?? I looked on this board but didn't find the answer. All advice, info & replies are greatly appreciated!!

check out the ammo oracle.

M855 is the cartridge. SS109 is the bullet.

www.ammo-oracle.com

" What is SS-109? Is it the same as M855?

SS-109 is Fabrique Nationale's (FN's) name for their 61.5 grain bullet with the steel penetrator in the nose and what they call rounds loaded with this bullet. (FN calls M193-type ammo "SS-92.") The US military's M855 round is loaded with the SS-109 bullet, though the US military has additional specifications that ammo must meet before it can be called M855. So, while all M855 is loaded with SS-109 bullets, all "SS-109 ammo" will not meet the M855 specs. For example, the British purposely underloaded some lots of their ammo in an effort to get their L85A1 (SA80) rifles to cycle properly. The ammo is still loaded with SS-109 bullets and labeled as SS-109, but it is nowhere near the M855 velocity specifications."

The SS109 is the name Europe gave the M855. SS109 "usually" meets the NATO specs(you have to look for that crosshair circle). The M855 is held to higher tolerances than the SS109. The US M855 is usually more accurate because the tolerances are more strict than the SS109 counter part. Example the steel core being centered better. The IMI ammo is VERY GOOD ammo so don't worry about anything. ALOT of people loved the ammo, but the sources are I think just about dried up. I don't know of any place that sells it(on the web).
Hope this helps!
Disclaimer I don't know evrything, some of this info can be incorrect. But yes look at the ammo oracle it is very informative. It been a long time since I read it.

Thanks for the info! I'll leave that ammo in the can labeled as SS109 because I know it's not NATO pressure. I guess I'll be picking up some M855, too.

IF I buy surplus ammo with the geen tipped SS109 bullets and LC headstamped cases, would that necessarily be M855? I get 2980 fps from a 16" barrel with good accuracy and small vel. SD's. Thanks.

That velocity sounds like NATO pressure to me for a 16" brl. The Lake City headstamp ammo should be M855, most of the LC ammo is XM855PD stuff it's OK ammo. Read the Top and second to last tacked thread it'll give you a good idea of it. The ammo man is selling real LC M855, pricey for 900rds $250. I picked some up but haven't shot it yet. Remember the US military M855 ammo is usually dirty looking with a bunch of small dings(sometimes) There are other sources to, browse this forum and you'll find some informative posts. Thou there is a company that that takes military headstamped ammo and reloads it,Talon company, this is not surplussed ammo I don't have any experiance with Talon Co. ammo.

Yeah, the Ammo Oracle needs to be corrected.
