i am looking for a smith that will rebarrel my left hand CZ American 452 .17hmr. I already glass bedded it a while back. I also have the timney trigger. I can't find anyone willing to swap my factory barrel for a Lelja Barrel. The smiths I've talked to say, the the 452 barrels are too hard to get off and that if I had a 455. They don't make a left hand 455. So, any smiths willing to swap a 452 barrel?
