I was also going to suggest an Encore pistol. In Indiana we don't have the straight wall restriction so we can use any of the Encore, Contender or XP-100's selections as long as your round is .243 or larger.

I love Ruger wheelguns also. I have a Super Blackhawk. But I think you should still go with an Encore. You can geta 15" 460 S&W barrel for it and if you can hold it still, you have 100 yard setup.

Good luck!
