X2 - Plus, if you ever decide to get a centerfire rifle, get a barrel and scope and you're set. Any standard Encore barrel will fit a Pro-Hunter receiver and vice-versa. A muzzleloader is a lot of fun and once you get a good load, very accurate. My .50cal Encore will shoot 1-1/2" 5 shot groups at 100 yards. There is a lot more work involved to muzzleloading than using a shotgun though. However, with the new slugs and rifled bores for shotguns today, you can have an accurate shotgun past 100 yards and it's a lot easier. So I would say you should look at an Encore with a 20Ga Pro-hunter barrel. If you want to try out muzzleloading, you can buy a barrel for later.
