To flute or not to flute?

I am told that this is too hot a round for this gun. Please advise. Thanks.

Where did you find WWB .30 luger?

I'm with Ron, sounds like a bigger issue- like a separated case.
What did the expended case look like?

A lot of hot gas had to get loose in your pistol to cause that much damage. I suspect "re-loads" hot or loaded till the case gave up.

Sorry for your loss.

It would really be good to start your own thread with pictures and not step on this one. JMHO.
