    Sounds like you're on the right track. The other way to fix it is to rent a .40 cal throating reamer from one of the reamer rental places (4D, elk ridge, etc).

    As side note, I as little lapping as I did to make a BTB 200 gr WFNGC work at 1.25 Oal. I think if I had just run a couple hundred XTPs or other jacketed bullets through the barrel it would probably chamber the BT's .... I'm guessing there were probably just some burrs on the edges of the lands. Hopefully I can get it out to the range and put a bunch of rounds down range, just won't stop snowing....
