USGI ammunition mfg before 1952 can be corrosive. USGI .30 carbine ammo has never been corrosive.

You should not reload brass cases from ammo that has been fired with corrosive priming. The residue can stay in the casing and cause the bore to corrode as if the original cartridge was fired in the firearm. Also, brass fired with corrosive priming can cause deterioration of the brass and cause brass failure when reloaded and fired. I have seen WW2 .30-06 brass fail this way when reloaded. Baking Soda soaking will not help this problem.

To clarify this....... All USofA Carbine ammo is non-corrosive. Back during the Korean War, China made a sh*t-load of Carbine ammo to be used in captured US M1 & M2 Carbines. The headstamp is LC 52 and the brass is CORROSIVE berdan primed. I hear some of this stuff is now showing up at gunshows. BEWARE......

You are correct ... I traded for some once fired M1 Carbine brass awhile back off another board. LC 52, berdan primed, was what I received. I was not very happy!! The fellow I traded with did not notice it was berdan primed ... He made everything OK in the end!! Still have several hundred pieces of the brass in my junk bucket ...
