Heck, most gunsmiths won't!
I had a .358 BLR, and I was chasing a number on the chrono and was into some major powder compression. Powder pushed the bullet out; round wouldn't chamber; and then when I went to eject it, it pulled the bullet out and dumped a whole caseload of long stick powder (3031 I think it was) into the guts of the thing. It was an absolute nightmare to clean. I'm sure there's still some powder deep in that action.
I take some pride in seeing people use Neil for this. When he dud mine, he hadn't done one in many years, but said, well ok, I'll do it I suppose. He charged me $75. Afterwards he said he made like $10/hr <g>.... I tried to pay him more but he wouldn't take it. I told him I was gonna put the word out, and he'd see more BLR's..... he said he was going to charge a lot more next time!
