I shoot the 250 Nosler Partition.....EASILY a 150 yd gun as I still have over 1000 lbs of energy. But, I am not hunting elk and stuff with it either. We have a doe season in Iowa that allows rifles and this is the fun lil gun to use at that time. I am probably in agreeance that 200 yds is pushing the envelope. I shot the heavy, long (24 inch) octagon cowboy bbl and that seems to help as well. Shoots lights out for a lever gun! It is just a plain fun gun to shoot, lil recoil in this heavier gun, plenty of gun for for all the small stuff and fun as heck to drop does with. I bought it for just something diffrernt then all my laser flat shooting stuff and I am having a blast with it, but respecting what it is as well.
