fter decades of hunting Ive came to the conclusion that the easiest way to set mine up is to put her 2" high at 100 which is about dead on at 200 and at 300 Ill have right at 6" of holdover and to me it just dont get much simpler than that and be as I graduated from the School of KISS {keep it simple stupid}and with this simple theory anything I want to take out to 300 yards will be DRT and I seldom find myself in a position of shooting game over 300 anyway...........
