while a buddy of mine was at the range, he was using lake city that he got from his dad, i know its really old ammo could date back to 90s but while shooting it would fire one round then not eject the cartridge and jam really bad, to the point where youd have to yank the charging handle. tried it with another AR same problem, he has the same gun as me stag arms model 2 with a .556 1:9 twist barrel. when he took home to clean there was actually a piece of the casing stuck in his rifle. he wants to throw out this ammo, but now a days thats considered going to hell for. is it that the ammo is too old or defective, i would hate to see 120 rounds go to waste.

some of it could be some Lake City rejects, but i'd still give it a few more shots to see how some others perform. could be a couple of shit rounds.

Ammo age when stored properly means nothing. I'm sitting on some wcc 5.56 from the early 80s that runs fine.
Improperly stored you'll have issues like cases cracking and head seperations due to brass embrittlement.
Properly stored just means in a good container away from large temp swings and wetness.

You absolutely sure it's not someone's reloads?

Lake city does not sell rejects in anyway that this could happen.

Fuck, do I feel Old!!!!!  
I guess I shouldn't mention that I still shoot RA 1954  that was handed to me by CMP way back to shoot matches(back when you shot on military base dam near for free, was handed ammo, and the GI personal where the ones runing the matches and even handling target changes/scoring), and still consider ammo from when Olin was running the LC plant still newer ammo as well.

Any who, Take a look at the ammo, and see if the primers are staked in or not.

If not, then chances are the ammo is reloads on LC cases,and might want pull them down to double check the loads and inspect the cases.

If the primers are staked in, then it's surplus factory ammo, and wouldn't let a split case neck stop me from shooting the rest of the lot so long as the ammo case are not in a bad tarnished/pitted state.

im almost positive they arent reloads, there were boxes for them and everything. could be due to how they were stored, im going to try them this weekend. he stopped firing after 3 or 4 bad jams

In theory nothing really should happen to ammo in a surplus ammo can.

Check the ammo to make sure they are clean and smooth.  While loading mags don't get grit on them. And make sure the rifle chamber is shiny clean You are probly already doing this.
Good luck.   I also hate to waste good ammo.
