Sorry I'm sort of late to this thread. It is fairly common for GI surplus LC carbine ammo to split, it is a combination of age and possibly some brittleness. I wouldn't have thought annealing was possible due to the straight, short case (splits run the whole length sometimes). However, it appears some with more experience than me have done it successfully. I always thought of annealing as something you do to the neck of a long bottleneck case. Good show!

Any temperatures you guys are shooting for specifically? I've heard of using an oven to anneal, more consistant across the batch. But since no temperatures have been stated I cannot tell.

Also, with the oil method, what about if the oil smokes profusely off of the case or catches fire?

Don't use an oven! That will also anneal the head and that is what you want very much to avoid!
