but I have come to miss shooting the traditional round ball over 60 to 90 grains of powder
Then save your money on another Encore barrel. You have one of the finest muzzleloading rifles on the market. Get yourself something traditional to shoot. Check out

I would also recommend the .54 caliber which is one of my favorite calibers. You might also want to look into the flintlock aspect of the rifle and really get some enjoyment out of shooting the rifle. It is a whole new challenge. Another nice rifle if money is not a factor is a Thompson Center Hawkins Flintlock Big Bore in .58 caliber from FoxRidge Outfitters. Then you have a rifle that you can do it all with.
