My friend, Stan, understands the basics of drop at comb, which many shooters have no idea about. Drop at comb is determined by the distance between the cheekbone and the eye, with some allowance for fat. 1 1/8 drop at the comb, for most shooters, means that the eye is looking at the rib from a well elevated point, very uncomfortable for most shooters of games other than ATA trap. Thanks, Stan.
