Re: need help guys. dont wanna waste ammo
Easy answer is 20 clicks. At 100, your scope adjusts for the labeled amount. Moving out to 200, it will move twice that, 300, 3 times that, 400, 4times that, 500, 5 times that, etc.
Divide by the factor to determine your clicks. As long as the drop is in the same calibration as your scope, you'll be close. A ballistics program will allow you to change from cms to clicks as a cross check.
