Lake City 243 Brass?

[06Shooter]

I was doing case prep on a batch of inherited 243 brass, most of which was stamped "Winchester 243", but one was "LC 72". Really? I have plenty of 30-06 and 5.56 Lake City brass, but I was always under the impression that LC brass is strictly surplus GI brass, and while I'm no expert, I've never heard of a military use of .243. (Actually, I don't have plenty of LC 30-06 brass - tough stuff to find nowadays.)

Strictly out of curiosity, could anyone shed some light on this for me? Oh, and by the way, this "LC" case cracked during a FL resize.


Thanks,
Chris

I am willing to bet that someone used a military 308 brass and necked it down to 243. That is the parent brass for the 243 anyway. I have done this myself to see if the cases would last any longer. Not any notable difference with these but if you anneal the necks before you size either of them them the brass will last longer by about twice in my 2 243's anyway.

It's a resized Lake City 308. You can make 243, 22-250, 25-08, 7mm-08, 260 Rem, 8mm-08, 35-08 and others from the 308 case. Heck, you can do it from the 30-06 case too or any of the offshoots of that- 25-06, 270, 8mm, etc, just need to cut to length.

All of my .338 federal brass are marked LC 82.

I've necked down some 308 to 243 just because 308 is trash to me. It isn't even good for trading around here.

I make my 300 Sav. brass from LC x51 brass,I got a couple 100 pieces for nothing and nobody I know could use it so I put it to good use.
