I have a KP1 in 45-70 (Green Mountain barrel) and it is giving me 3/4 inch groups at 100 yards. I would like to purchase more barrels for this rifle but before I do I would like to know if I can expect the same accuracy out of other barrels. I am really pleased with the accuracy out of my barrel and hoping that this is the norm and not a fluke. Anyone out there shooting these rifles and getting good groups out of them?
