any of you guys know a gunsmith who has a "finish reamer"? i need to have my barsto .40 barrel reamed. this is what some guys at benos forum advised me to do: The Bar-Sto's I've had, I've had to go from a .420 crimp to a .418 and that helped. When I went to the tighter crimp, I didn't see any pressure signs to worry about and it didn't hurt accuracy... But some I've had to ream a little. The lead bullet dia. is about .002 bigger than jacketed. If the throat is not reamed for lead it won't go in. You need to use a .402 chamber reamer to run in the chamber. Most custom smiths use this reamer so the guns will run anything from jacketed to lead. They make 2 reamers, one that's .401 & one that's .403. If your chamber was cut w/ the .401, it was set up for jacketed only & needs to be re-cut w/ the .403 for lead. Lead is about .402 & won't alway's feed in the smaller chamber. The throating reamer is made by Clymer. I would call around your area and try to find a gunsmith that might have a throating or finish reamer, because reamer's aren't cheap. so do any of you guys know who has a ".403 finish reamer"??? thanks a bunch Wanna kill these ads?
