Carcano M-38??

I'm no expert but the spent casings look like the spent casings from most of the rifles I own, both civilian and military. Some expansion is normal, the chambers are larger than the cartridges and this is by design.

My military rifles in general show a larger degree of expansion than my civilian ones although the most extensive is from a Savage 99 lever action. I still carry that hunting occasionally and check the casings after each firing, no evidence of separation and no primer issues.
