Help ID primers from LC 4 30carbine brass

[Reefinmike]

Hey all, I had 700 pieces of primed(Im assuming pulldown) 30 carbine brass. Headstamp LC 4(1944) brass is unfired and primers were all sealed with red lacquer messier than any google images I've seen. Primers look pretty modern with the brass anvil not being tarnished as well as the color coded anvil. I have also found a couple pieces of possibly corn cob media in the anvil's cup after decapping.

I'm thinking that these are more modern(probably late 80's to early 90's) considering the sloppy primer sealer application and the possible media found in the primer pocket but it is possible that these are original primers as google images pulls up some LC 4 ammo with nickel primers. I'm asking to determine whether these are corrosive or not. I was planning on burning these up in some light 38spl loads.

Mike,

USGI .30 Carbine ammo never was made with corrosive primers, so use them without concern.

Yep, that's one U.S. military caliber from World War II that was never manufactured with corrosive primers.

Hope this helps.

700 rounds of boxer primed carbine brass. I'm jealous.

ussr and reloaderfred- thanks for letting me know, I'll use them without worry. Im curious as to if they are the original primers or not.

hdwhit- there were a couple thousand more of other lc dates as well. they've all since found good homes.

Those do not look like USGI primers. Most likely someone reprimed pulldown brass so they SHOULD be non-corrosive. USGI ammo never had corrosive primers but if these are reloads there are no guarantees. Fire a couple onto a clean steel plate and see if it rusts.

The brass could have been reloaded and the primers sealed with fingernail polish. There is a narrow window to time to wipe the fingernail polish off and get a perfect ring around the perimeter of the primer. Wait too long and you will get smears that look like what is shown in the photograph.

I seal all of my primers in place with fingernail polish. When I first started doing it, I used red, but soon switched to black for aesthetic reasons.

Reefinmike - there was a time when every piece of 30 Carbine brass was precious, so I still to have a visceral reaction to it. I no longer own an M1 Carbine. All of my remaining 30 Carbine brass will in time be turned into cases for 5.7 mm Johnson (.22 Carbine) and with all the effort that goes into cranking out one 5.7 mm Johnson round, I think I've got enough brass to last me for the rest of my life.
