About a year and a half ago I bought a new "JM" 625 revolver. Had wanted a 45 acp revolver for quite some time. Loaded some cast bullets and got all sorts of lead in the barrel. Sent gun to S&W for repair. Got gun back. Forcing cone had been opened up to the point that a 45 caliber bore brush would not make contact with it. Plus, the leading problem was still there, (that's when I noticed the bore brush wasn't making contact). Sold gun for a substantial loss. Question: Has anyone else had this problem? The good thing is that My K frame and L frame guns shoot cast bullets flawlessly. Forgot to mention I ended up getting a Ruger Bisley Convertible and after having the throats for the acp cylinder opened up by Bowen Classic Arms, I have a very accurate gun.
