FIRE LAP -FORCING CONE QUESTION

[30calpal]

I have had Cylindersmith ream the throats in my Bisley 45. I have read Iowegan and Veral Smith. I have acquired the forcing cone chamfer cutter (11*). I am seriously considering fire lapping to remove the constriction at barrel /frame juncture. The QUESTION is: Should I first fire lap then chamfer the FC or chamfer FC then fire lap ? Input is greatly appreciated.

after the restriction is gone to your staisfaction then do your 11 deg Forcing cone and polish it smooth. Sizr your bullets acorfdingly and use a good crimp and all should groop well. J.Michael
