RE: revolver vs T/C Encore
I have revolvers and a T/C Contender and Encore. The revolver gives you 5 or 6 shots ( never needed more than 2) and it balances better than either T/C with or with/out a scope for off hand shooting. I have a Ruger Redhawlk in 44 mag with a red dot and a Ruger Super Redhawlk in 454 with a red dot.
The T/C's only give you 1 shot but they are a little more accurate and I normaly need only the 1 shot. The Encore can be had in many pistol and rifle cal so it can be more than a 1 season gun ,just change barrels and go chuck or yote hunting. I have 15+ barrels for the Contender ,I use the 44mag for deer. The Encore I have a 308 barrel and a 375JDJ.
Any of the cal. and guns will do every thing you have listed, now its up to you to chose.
I tryed a S&W 500 its to big and heavey ,to much boom,to much $ per shot for my liking
