My new rifle got here last week took it to the range and WOW I'm about ready to throw it in the river (not quite Knight has too good of a service dept for that) started 100 gr pyrodex, .430 240 gr rem bullet (don't knock it shoots in my MK-85s, the wolverines, big horn and T-bolts I've had), shooting sort of ok 3.5" at 50, powder ran out, opened new can went to 6" groups, went and got a new jug of T7 back down a little, bore felt rough so I went ahead and got a pack of power belts to rub the lands a bit, last 4 shots 90 gr T7 and 245 gr power belts was 4". I will grant that in my experience power belts don't shoot as well as sabots in Knights however this is not good. I called Knight and got the shoot the .451 bullets in the black sabots, just wondering about someone elses opinions
