If you can find a used TC Encore, that would be my first recommendation. The frame is considered a firearm, so it is a bit more of a pain to purchase, but they are solid performers. Plus, if you decide that muzzloading isn’t for you, they are easier to sell on the used market, or just get a rifle barrel for it and hunt with that.
If you don’t want to go that route, then I would have to say CVA is probably your best option. I am not familiar with the recent barrel issues noted above, but they use Bergara barrels, which have a great reputation in both the ML and rifle community.
