I spent a little time at my range today shooting 500, 600, and 700 yards. I am using a 338 Kahn topped off with a Night Force NXS 5.5X to 22X. This is a new scope that I have only had a few weeks and have just now tried dialing up the elevation on it. In all my previous long range shooting I have used mil dots or other multi-range reticals rather than dialing up for the yardage. I noticed that when I dial in for a new (longer) yardage that the first shot of a three shot group hits about 1 click low. The next two are dead on. This happened to me on each of 4 yardage dial ups. Is this typical? Should I go two or three clicks past the correct setting and then go back? Do I need to tap the scope to ensure it settles into the correct setting? Do I have a defective scope? Thanks in advance for any guidance anyone out there can provide.
