Sorry, I must be having a brain cloud or something. I dont usually shoot at 1000 but, last month or so did it for the first time. Now, I am going to do it again Oct. It was just so much darn fun. So, I have a few questions about going to a 20moa base. Now according to JBM for my 6br Norma I will need 10mil for me to get to the target at 1000 using the inputed bullet, fps etc etc. My flat base Zeroed at 100 yards only gets me just a smidgen over 9mil. till maxed out. Now according to Leupold the V3i LRP 8.5-25x50 has 80 moa adjustment. So, that would give me roughly 40moa at mechanical center 40up/40down correct. If 10 mil equals 33.75moa why cant I get to the needed 10mil but, only 9mil or 30.75 or so moa. So, at 100 my needed mils are currently wasted in down and not used which would equate too 2 mil or roughly 6moa I am lacking? Am I correct to assume if I go to a 20moa base I will still be able to get zero at 100? I dont shoot a long ranges (or atleast 1000 often) so, its important I can still zero at 100. The perfect scenario would be the 20moa gets me to both 100 and 1000. Sorry, if this was not explained exactly as needed but, hope you get the jest of my question.
