Great shooting! I just got a new Ruger Blackhawk Bisley 7.5? 45 Colt and am about to use Hogdons data to work up the same load. Did you get lucky and harvest a deer with that load, and if so how did the bullet perform? I have three boxes of the 250gr XTP so I am very curious about on game performance at the h110 speeds in 45 Colt.After six differnt loads and two trips to the range today I finally found the right recipe 250 gr XTP, 26.5 grains H110, starline brass, winchester large primer. First group at 25 yards 1 1/8 ", (group on right) minor sight adjustment 1" group on second attempt(group on left). Keep it under your hat, don't tell the Nebraska muledeer about this-they only have nine days of peace left.
