I'd like to hear how you calculate to make your long range hunting shots in the field. Using the following list of equipment: Precision long rifle (7mmLRM for this example) Leica 1600-b, Kestrel 4500, Vortex 6-24 PST MOA scope and the "Shooter" app on my phone. If you have a custom turret made for a certain weather condition (humidity, altitude etc...) and you find your self in different condition, whats your method for correcting for the new condition? I'm thinking that you would just want to stay with a standard MOA turret instead of the custom turret? I know that if I had the G7 BR2 rangefinder that it would correct for me, but for this year I will be using the list of equipment stated above. Step by step, whats your procedure? And would you prefer custom turret or standard turret?
