My vote is for the Single-Six.
For an intro, I own two stainless Single-Six revolvers. I've looked at the Taurus revolvers, but have never shot or owned one. I'm also not a coon hunter.
For .22s, I prefer stainless and adjustable sights.
One of my Single-Sixes is the current "Lipsey's special" with 4-5/8" barrel and adjustable sights. I believe Ruger catalogs the same gun in blue, but the stainless is a limited run. I paid $329 for mine at Cabela's.
-I presume most of your shots will be at short range. The short barrel should give you adequate sight radius for sufficient accuracy.
-The Single-Six gives you the option of the .22WMR cylinder for a little more power. The extra power of the WMR might come in handy, I don't really know. Just a thought...
-As far as loading goes, I don't think the single action will hamper you that much. Loading isn't that difficult after familiarization, and you probably won't be making enough shots to make speed a major consideration.
I'm not necessarily anti-Taurus, but I think the Ruger might be a better firearm. I have had EXCELLENT service from every Ruger handgun I have owned.
Good luck!
