Nice article and pictures! I never thought about the Redhawk being a good alternative to the custom 5-shooters, but it makes sense.
Jack... beg, borrow, or steal a copy of Hodgdon #26 loading manual. It is the bible for .45 Colt shooters in modern handguns. Their loads go up to 30,000CUP, which is generally acknowledged as a reasonable limit for the .45 Colt in a Blackhawk.
The Redhawk is a beefier gun, as the article notes, but data for it is scarce.
Personally in my Bisley Blackhawk I run the 300 WFNGC's at just over 1200 fps (not really max), some 340gr custom flat-nosed bullets at about 1150fps, and I don't mess with the 255-260gr bullets for hot loads. Too hard to get reasonable velocity spreads with the light bullets.
It does sound like you have a little room to grow on your loads. Good luck.
