In my opinion, find another 'smith. You'll probably never know why this happened, but on this rifle it was grossly negligent, or incompetent.
1. Huge mistake on headspace. There are at least 3 test stages during chambering that will
catch headspacing error. I don't know how anyone could miss all of them.
2. He couldn't have tested it for feeding and extraction. It would have done the same
that it did to you. Even without firing, it still would have failed to pick up the rim and extract.
3. It should have been test fired before turning it over to you. All of the problems you have
would be discovered when it wouldn't fire. Even though some shooters want to do all the
barrel break-in, any custom rifle
should be test fired by the builder, with agreement in
in advance, especially a boomer.
4. I don't want to pile on, but jmden and Big Mick got it right, you should never have fired it. You
can get away with a lot of mistakes on a .22 Hornet, but not a boomer like the Edge.
Extremely dangerous. You were very lucky.

Good luck and good hunting, Tom
