squirl:
Thanks for the explaination, though I must confess I've never seen or heard of anything like that happening in my circle of hunting friends and aquaintances!

My initial reaction would be "chuck the bloody thing away!", but as 500Nitro is quick to point out, I'm happy to attempt restoration on just about anything worthwhile! The question is, does that primer-setback failure represent poor metallurgy or lousy materials and workmanship throughout the rest of the gun? Certainly cause for concern IMHO.

Anyone else seen this?
