Techie results in better shooting and ethical kills. I have only got into shooting at extended ranges in the last 6 months. I will say that turrets matched to your load are pretty much worthless if you have temperature fluctuations, elevation changes, angle of shot(up or down hill) or wind. I run moa turrets and dial my minutes based off ballistic programs in the field(or cheat sheets tailored to the conditions I'll be in). Also the cds dial I had leupold make wasn't even close to hitting a pie plate at 500 yards(almost a minute below it)even though I gave them all the data for my chronographed handloads. So went to moa dials and ballistic programs and a notebook. However you must do the shooting first and verify you poi at these ranges and then modify your data within your program before hunting. BC's are often falsely inflated by the manufacture, and a chronograph is a must. I would look into a good ballistic program, work up a good load with a high bc bullet, then hit hills and find places to shoot out to the max range u are going to be hunting. Put all that data back into the program through a targets list and find the true bc of the bullet you are shooting. It's really all relatively simple, thanks to technology.
