I’ve a chance to buy, locally at that, around 250 rds and maybe more if this ammo. I remember several years back that some questioned the quality of this ammunition. I can’t remover exactly, but is it overall safe to shoot?  I think headstamps are PS 75, maybe 77 or so. Thanks in advance.

Here is what you desire, but note that I compiled this list based on REPORTS from contributors to this and the CSP forum (jouster.com). This list is not the result of "scientific research" and/or testing. Reports were postive unless noted.

But, anyway, here it is:

PS 2-088
PS 2-090
PS 2-093
PS 2-094
PS 2-097
PS 2-098
PS 2-100
PS 2-101
PS 2-104 (one positive report based on very few rounds fired)
PS 2-105 (one positive report based on a few hundred rounds)
PS 2-122
PS 2-124
PS 2-127
PS 2-128
PS 2-135
PS 2-144
PS 2-145
PS 2-146
PS 2-147
PS 2-148
PS 2-149
PS 2-151 (Maybe OK - based on VERY limited information)
PS 2-152 (VERY Bad - numerous reports of ruptured heads!)
PS 2-154 (Some positive reports / negative report [splits] based on sketchy info)
PS 2-155 (Bad - one report of splits 2 out of 250 rds)
PS 2-156 (??? - there are reports it's fine - one report of splits)

PS 2-181
PS 2-183
PS 2-184
PS 2-185 (One negative report but only on hearsay)
PS 2-186
PS 2-187
PS 2-192
PS 2-193 (??? - some of this lot badly corroded)
PS 2-194
PS 2-195
PS 2-198
PS 2-204
PS 2-205

I take it these are lot #’s of ammunition?

Yes...it was PS 75 that had issues.  If its in the original packaging the lot# will be visible.  If its not PS 75 then it should be fine.

Worse case is it IS PS 75 and loose.... buy it for scrap price then reload the powder and projo into new brass.

That’s my plan, I just needed the year of manufacture. Thanks!

Keep in mind not all Korean M2 was PS headstamp.  KA was also brought in at the same time and although mostly good ammo it is to be considered corrosive.

Korean ammo is good stuff.  Like posted above PS is noncorrosive & KA is corrosive.  I've shot a bunch of both through my Garand & 1903, just clean well afterwards.

Years ago I bought a couple bandoliers of KA headstamp M2 ball. I asked the guy if it was corrosive and he lied to my face and said no. I looked it up and it is corrosive, this was before I knew the difference.

Corrosive ammo is still good ammo.  Clean your rifle.

I have some cans of this stuff.

Delinked in a Korean can, mixed HS.  I'll look for PS75 but is there anything else that needs to be looked for other than obvious corrosion issues?

Is this delinked ammo the same load they use for M1's?

thanks

Yes, no such thing as "MG ammo"

KA headstamps are corrosive primed FYI.

Thanks

I dont know about 30 carbine but PMC used PS on lot numbers on 7.62 M80 ball. It been great stuff I bought pallets of it back in the 1990's
