This was a 30 cal 200 gr AB out of a 1 in 10" twist barrel. I figured that the muzzle brake might have been installed incorrectly and the bullet was kissing it on the way out so I took it off and proceeded to keyhole another bullet!
I called the guy and he gave me the runaround but that is another story. He has been given an "F" feedback by the way. I figured it just needed to be recrowned but when I threaded the brake back on I could see that it was wobbling around. Looks like The threads and all need to be chopped off and the barrel recrowned. It didn't kick too bad without the brake so I probably won't spend the money to have it rethreaded.
Does that sound like the next step or are there any other possible causes of the horrible keyholing? I'm sending it to a gunsmith who does barrel and brake work and he is going to check everything out. Looking to take the lemon I got and make it into lemonade!
With only .020 thousandths clearance through the brake if it wobbles when screwed on
my guess would be that the break is the problem.
I had The same thing on a rifle that I bought for a don,er . when I unscrewed the break
it was badly out of alignment and upon closer inspection the barrel had been threaded with
a die nut instead of on a lathe. the guy had done it himself and screwed it up so he sold
it to me for next to nothing.
While looking at it I noticed the copper fouling in the break and knew there was a problem
but did not need the barrel or the break and ended up with a very good action and stock.
One other possibility is that the "smith" screwed up and installed the wrong barrel. I know
it sounds impossible but I was ask to check out a friends rifle that he bough from a gun shop
and found it had a bore dia. of .312 instead of .308. and after he confronted the gun shop
owner he said it had a like new military barrel but he though it was a 30 cal.
With a 1 in 10 it should work with the break off. so it will be interesting what the problem
really is so please let us know.
