Drilling and Tapping Blackhawk

[propliner]

Has anyone here mounted a Leupold scope mount on a Ruger Blackhawk? I'm just wondering what it looks like when all is said and done. Also, does anyone know the screw size for the mount? They are the same as the rear sight screw. Does the mount sit in the rear sight groove, and is it supposed to hang off the topstrap and almost over the hammer?

I have the mount and am ready to start but I'd like some advice (and would really love to see some pics).

Thanks all,
Props
