Checking casings

For the straigh cases like the 45-70 and M1 Carbine what should I be looking for as an indication of pending case failure? The 45-70 is in a trap door so the load is fairly light. Do these cases tend to fail length wise or at the base?

Thanks

  45-70 will usually split at the mouth from work hardening before head seperation just ahead of web. Taletail sign is bright band about 1/4 inch ahead of rim. I have some that went 50 + times before the primer pocket wore out. Buy the brass without the channelore, it delays the first trimming. Aneal the neck every so often to help make brass last.

  Thanks for the info. I'll have to take a look but nice to know where to look. I check the web on anealing brass just to make sure.
