i guess i am only one that does this. many bucks have been missed because of using wrong line for yardage. what i do is sight in 1 line dead on at 20 yards.if buck is at 10 ,i aim a little low,if he is at 30 i aim up the shoulder a little higher.never take shot over 30,never had too in archery.this way i dont get mixed up on wrong line for yards. i hear so many stories of hunters using wrong line on yardage.this takes 1 problem out of the hunting. anyone else doing this?
