I have a Zeiss 6-24x56 scope on a 300 Jarrrett. I am shooting 180 AB at 3280 FPS. WhPen verifying drops out to 1300 yds I am having to play with Shooter a bit more than usual to get a drop chart to match actual results when shooting. Aside from the playing with the BC and MV, could my scope inputs be causing the error? The scope utilizes .5 cm per 100 meter clicks. It never dawned on me that this is not the same as .2" clicks per 100 yards or 1/5 clicks on shooter. Do I need to enter a custom click value? If so what is that value? or am I just confused?
