I was doing some research on rifles and muzzleloaders when I came across the TC Encore and Rossi Wizard, for which you can buy different caliber barrels. They seem like a good idea because you have multiple guns in one. I want to know if any one has any experience with either one or both?

Thanks Guys or Gals

Don' know about the Rossi , but have been shooting TC's since the 70's, I really enjoy them, the older contender ,and the Encore, haven't tried the new Contender G2.Most of the barrels I have are accurate ,all are accurate enough for hunting.
I probably like the Contender a little better, it's lighter,but the Encore allows more caliber choices, and will take anything most people would care to shoot.I've had mine foe awhile ,even the Encore was bought the first year they were out, and I have heard some complains about the newer one,those made since S&W bought the co out. Don't know just what I've heard. Will probably never know unless one of my friends buys one, I think I've got all I want.
For more info you might check out Specialty pistol forum, it's a lot about single shot pistols, and there is a lot of knowledge there.

You may want to take a look at the NEF and H&R single shot break open rifles and shotguns. They come in several cals. and gauges and muzzle barrels. They also have barrel program where you can order other barrels for them.

what about a CVA APEX, I have one in 300 win mag and it's the best rifle in my opinion I own

CVA APEX 300 win mag is damn hard to beat
