Mawgie,
I'm a single action revolver man myself but since you already have the Encore that may be the way you want to go. You have a much larger choice of calibers, whether stock TC, or custom barrles.
I would suggest a scope for the over 100 yard shots, and a scope looks much better on a Encore than on a single action. To me a scope on a single action reminds me of a Corvette, I once saw, with a 5 wheel hitch on the roof; works fine but just don't look right.
I do have a 5 shot, custom Ruger SA, with iron sights, that will shoot a 2" - 100yd group off a rest, if the wind, sun, humidity, the moon is right, all stars are in alignment, and I've drank only one cup of coffee. I have even shot a 1 1/2"- 3 shot group with it.
If you are going the revolver route you may what to check out a Ruger Bisely in 45Colt. With handloads you can out preform the 44mag a little bit.
