I'll warn you that it isn't just a load and shoot deal with a muzzleloader. They can be and are very accurate out to long ranges. My longest kill was a nice bull in New Mexico at 273 yards. 300gr Parker pushed by 90grains of BH209. Muzzle velocity on that load is 1800fps and it will print 3-4" at 300 yards. That is in a Savage ML2. If you want accurate, I would suggest Knight.
But, it took a bit of trial and error to find a sabot/bullet/charge combo that worked. They can be temperamental bastards, and you have to pay attention to temperature of the barrel and sabots to get the best out of them. Too warm and the sabots get soft, strip in the rifling, and you will just get frustrated.
I would suggest looking in the muzzleloader section here for tips and tricks.
20 gauge sabot slugs are an easier way to go, even with the recoil. Just my opinion. I've had H&R handi-rifles in 20 gauge and a couple of 20 gauge Mossbergs with rifled barrels that were all about 1.5" at 100. Enough for 200, but not quite enough juice past that.
