I picked up a rifle on gunbroker. Seller said in auction that he would provide the name of gunsmith to winning bidder, he never did. Long story short, I bore sighted and couldn't get on paper at all. Tried again the next day with more ammo and finally got on a great big piece of cardboard at 50 yards. Only problem is that the bullet went through sideways. 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. 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!
