I have been trying to research the claimed advantages of cutting an 11-degree chamfer to the forcing cone on an 1858; when converting a percussion revolver over to cartridges. I understand in part, it's supposed to cut down on "shaving lead" when you use a cartridge as opposed to percussion ball and in theory make the gun more accurate.
I read elsewhere (I reseached here... but didn't find anything) that an 11 degree cut makes an improved difference, especially when going from .44 cap and ball to .45Colt cartridge (which is what I did).
Has anyone actually done an 11 degree cut to their forcing cone?
Secondly, what is the "standard" forcing cone cut, on black powder 1858's? In my case I have a CVA made in the 1970's... but I also wonder about Uberti, Pietta, etc. I imagine they are all close to the same, when manufactured for black powder percussion.
Knowing the difference in how a BP cone is cut, compared to how a cartridge forcing cone is cut and looks would be quite helpful to better understand this.
I found this particular video helpful to understand the process and thought I would just share it: http://www.youtube.com/watch?feature...IBv6VIQGE&NR=1
I see that Brownell's sells a 11 degree chamfer cutter tool for about $52 bucks.
They state: "No Lathe Needed, No Need To Remove Barrel From Frame. Recommended by Ron Power. The gentler entry angle causes less bullet deformation and gives better accuracy (especially important for "wadcutter" shooters). One size for all calibers from .38 to .45."
If doing such a cut is worthwhile, I'll spend the money and do it... but just don't yet understand enough about the differences between the black powder and cartridge/boolits angles to move forward.
