Hello folks,
I have fairly new S&W 627 PC .357 revolver that may have some forcing cone issues.
I wanted to ream the deep machining grooves out of the forcing cone with an 18 degree reamer from Brownells - to correct SWC leading problems and improve accuracy.
Before going down that road, I checked the forcing cone with a .38 11- 18 degree plug gauge and found that the high end (large diameter) part of the gauge sinks down below the outer mouth of forcing cone face by about 1/16-inch.
From everything I've read on the forums and in Kuhnhausen's manual, the outer mouth of the cone has been factory cut is too large.
So my question is what to do now???? Is this a problem? Is it within S&W specs? Is it a warranty issue? Do I have the wrong plug gauge?
Any advice will be appreciated .....
