It seems that both loadings I'm making for my 7.5" bbl Blackhawk in 45 colt, shoot to the same point of impact at 20 yards. Is that unusual? I've been loading the Lee 452-300-rf and experienced uncanny accuracy with the first loading I attempted. Not wanting to change anything, I've stayed with that exact recipe. I've since aquired the Lee 452-255-rf and although the powder charge I use is slightly larger (Hs-6), they appear to share the same accuracy (@ 20 yards) and point of impact! I plan to load the 255's in much larger quantities, since they are more economical and don't require gas checks. I'm confident that whatever crosses my path on our Texas ranch will be easily dispatched by the lighter of the 2 boolits. Right now, I'm happier than a wild hog, wallowing in the muddy tank on the ranch!
