I have one and I love it. My girlfriend (fiance as of last week) got it for me as a housewarming gift a year ago. I have taken one deer with it. I am shooting 2777 pellets topped with a 245 grain areo tip powerbelt bullet. I am 3 inches high at 60 yards and dead on at 115 yards. I could not get as good of performance with the 295gr powerbelt bullets out at the 100 yards mark.
The only thing I have noticed, Iuse a brass cleaning jig a couple times to bust up the crud ring when I am at the range between shots. I will then use a wet patch and two dry patches. This gives me the best accuracy. Ihave also tested at the range by loading a second shot without cleaning.The accuracy is not quite as good, but I feel it is acceptable if I need a follow up shot on an animal.
Have fun with it and I have got some great advice from this forumthat made my muzzleloading more enjoyable.
