Arnie,
I'm glad you are thinking about handgun hunting. I've been at it for about 5 years and have thoroughly enjoyed my Contender in a 7-30 Waters which I consider to be a solid 200 yard performer on whitetail assuming I would have a solid rest. Recoil is mild with the 7-30 out of a 14 inch Contender barrel. Accuracy is 5 rounds in 2 inches at 200 yards. Its a sweet rig. I've not hog hunted so I can't speak on how well a 139 grain bullet moving 2150 fps would do on them.
The Contender is no longer being made but new frames can still be had but supplies are drying up. The Contender is able of handling potent rounds such as the 45-70 and 375 JDJ. There are backthrust and pressure issues that prevent it from safely shooting rounds like the 6.5X55, 7-08, 30-06, etc.
The Encore is a newer single shot pistol from TC and is readily available. It is beefer and capable of handling most rounds that you would dare to load and then pull the trigger. I would think an Encore in a 7-08 or 308 would be awesome on hogs and whitetail. (I would go with a 30-06 simply because of my love of the round.) Obviously, such rounds can reach out and touch at 250 plus yards.
Rugers chambered for the 44 Mag or 454 Casull are certainly 100 yard performers if the shooter is up to it. The Casull can tack on another 50.
The advantages of the TC: Very accurate, interchangable barrels, outstanding effective range out of a pistol. The disadvantage is that they are fairly large weapons.
The advantages of the Rugers: a bit easier to handle and shoot off hand, quick follow up shoots. Disadvantages: more limited range, one chambering only.
If you move in the TC direction please know that there are a lot of fine, helpful folks in Graybeard's TC forum.
Blessings!
