There was an old saying that the Number Ones with the barrel bands were the fussiest ones, as far as accuracy. If they had tight spots, I can see why!
I killed a doe Saturday with the Ruger. The load was a stout charge of 1680 under the 123 SST. She was about 85 yards away feeding, quartered toward me. I held on the near shoulder, but hit slightly in front of it. She jumped about 6 feet up when hit, and ran about 60 yards. The bullet had caught and ruined the front of one lung, cut some big blood vessels, then went down and exited the brisket, and broke the offside leg. A copious blood trail made the track pretty easy. It seems it works fine on our small deer, though I want to try better placement next time, and maybe different bullets.
