Re: newbie needs help
You may also need to box test your scope, meaning to check that the knobs are actually moving the reticle as advertised. I recently did this with my Vortex PST to check if it was the scope (I am having similar issues with the POI being slightly high for what the program says):
1) Create a LARGE target with precisely measured impact points for a set distance. I used 50 yards, with a 1 mil grid spacing (1.8" at 50) since my scope is mil/mil.
2) Set the scope to that range zero at the bottom of the target (bottom since you will be dialing up for all long range shots).
3) Dial the scope up, left, right several mils or MOA, depending on scope. Aim for the bottom target dot at all times.
4) Verify that the groups are in the proper impact points for several combinations of offsets.
FYI, my scope was dead on...so I'm still searching for the reason. I need a chronograph, I guess. Or maybe I'll just fit the curve for the loads.
