As far as Muzzle loaders go, I have had an Encore and some hunting buddies have also owned them. I have to tell you that none of them will hold a candle to a Knight Muzzle loader. The only advantage is that they have interchangeable barrels, but as was stated before, you will get alot better accuracy if you put the money into a GOOD rifle right from the start. Your 8mm should perform fine for you, so if you want to invest in a truely awesome, accurate muzzleloader, buy a Knight!
Just my 2 cents.
