I made a trade (on another website) for some .30 Carbine brass. In with the cornucopia of brass was 10 cases with "LC 52" head stamp that were Berdan primed! I assume this is the Lake City Arsenal. I've never seen this before, though I don't make a habit of looking at early '50s .30 Carbine brass. See the picture below. What's the deal?

It's pretty common for milsurp brass to be Berdan primed. Especially brass from 1952, which that is.
My experience with American military brass is that it is boxer primed. I've never had any that was Berdan primed, until now.

I think the Chinese made LC52 knockoff ammo for the Korean War. I broke a deprime pin on that crap.
It is for sure Chinese made LC52 brass. It was berdaned primed and very corrosive. It's really hard on the piston assembly and seeings how the pistons are staked in on the M1 and strip quite often if you try to remove it to clean out the corrosive salts, it is generally recommended to NOT fire it in an M1 carbine. If you try to reload it (why would you, its berdan primed) clean them with soap and water to remove the salts.
i found a bunch of them with that headstamp in a batch of carbine brass i bought last year. i just tossed them in my brass bucket as i found them. i thought it weird that lake city would use berdan too
They only changed to boxer in the 50's, and probably only because they didn't want the corrosive primers any more.
