The Encore is a great rifle, which will allow you to add additional calibers later. However if you don't forsee needing/wanting to do that later, the Encore has quite a bit higher price tag than other ML's that are just as good or even better without the cost.
I am not trying to talk you out of the Encore, just suggesting an alternative view.
Whatever you decide to go with I would suggest you look at trying Black Horn 209 powder. It is the next thing to smokeless powder in a muzzleloader. It allows many more shots between cleanings, while still maintaining accuracy. It does however require a rifle that uses a 209 shotshell primer.
Here are a couple of links with some good info.

Hope this helps
