Once I get the Colt New Service revolver out of Commiefornia 10 day jail, and get all the components lined up, I plan on doing a .455 Webley reloading data article, that hopefully the Mods will make a reference sticky of. I plan on comparing several loads - minimum and maximum- of each powder (WW231, Unique, Bullseye, Triple 7) using the 262 grain hollow base Bear Creek Supply Webley bullet. Might do also do a .454 200 grain RNFP too. Probably only do 10 to 15 yards, as my 73 years old eyes and hands don't do too well any more on Bullseye shooting.
