You have a great gun. I am new to muzzleloading and have a Disc Extreme also. You may want to try Barnes Expanders 250 grs. I shoot 130 gr Pyrodex pellets and get 2" groups at 200 yards with the combo. I have killed 8 deer with this combo; the best being a 178" Oklahoma whitetail from this past fall. All the deer have dropped in their tracks. Congrats on a great gun--Happy Shooting!!!
