Hi Guys, I could use some help with my new set-up. I am new to long range shooting and am experiencing "lack-of-experience" issues. I am shooting a 300WSM HS Precision which is new. I topped it with a Nightforce NXS 5.5-22 scope on a 20 moa NF base. I dialed in the scope to shoot zero at 100 yds... nice 3/4 inch groups with Winchester supreme 180 gr. e-tips, shooting off a back-pack on a four wheeler for a rest. I decided to give a long range shot a try.... backed up to 450 yds, using a ballistic FTE calculator on my iphone it showed a bullet drop of -33 inches. So, I dialed my scope up 28 clicks or 7 MOA.. I torched off six rounds and got a 8 inch group that had a POI eight inches high....... What did I do wrong besides NOT following the well written article on setting up a new outfit found on this site? All comments are welcome including the smart-alec type....... Thank you For clarification, I am not concerned about the grouping, but rather why the group at 450 yards was high by so much, I have never used a scope with tactical turrets and am concerned since I got a decent group but too high POI I did something wrong??
