Sorry about the disappointment. I am just guessing but they probably re-cut the forcing cone because they found it to be out of spec. As to the honing of your cylinder, you really should have sent the gun to a pistolsmith who specializes in this sort of thing. S&W makes their guns to shoot factory ammunition, which these days is mostly jacketed. They are probably not going to pay too much attention to requests to modify the gun to shoot certain types of handloads. It's not their thing. They are a manufacturer. Pistolsmiths probably best handle this sort of stuff. Sure, a little communication would have been nice, but that is not unusual for them. About one call in four to Springfield ends up satisfactorily as far as my experience has been over the years. The other three make me wish I was running their C.S. department () - but, as I have said before, I can only imagine the kind of calls/requests they must get in the course of a day. Probably would baffle the ordinary mind.
