I wonder if most people would tend to shoot a Ruger Redhawk or Super Redhawk more accurately than a Ruger Blackhawk or Bisley. I understand that a double action has a shorter locktime and so that should help to give smaller groups. I also wonder though about the grip differences. From what I have gathered most serious big game hunters use single actions, either the Ruger or Freedom Arms, so most must be able to shoot them well. I have a Ruger Bisley in 45 Colt and have not been able to consistently shoot small groups unless using my scope and a sandbagged benchrest. The gun is very accurate but I am not shooting it well. With a 2x scope attached and shooting from the bench with sandbag rest I can often get 2.5” to 3” groups at 50 yards. But without the scope my groups open up quite a bit. They are more like 2.5” at 25 yards. I will often get 3 shots in less than one inch but then the other shots will open up the group substantially. I am doing my best to be consistent but obviously am not. The shots that open the group up are usually high but not always. Sometimes they are low and sometimes they are right or left. Most often though is that I have vertical dispersion. Are double action grips easier to grip consistently? If I were to get a double action I would probably want one chambered to 454 Casull but would figure on mainly (probably only) shooting 45 Colt loads in it. Would accuracy suffer if I shot 45 Colt loads in a 454 Casull chamber? Thanks, Brian.
