FOTIS":mbcrx3q3 said:Also Lyman used to use a formula where if your rifle six inches low at say 50 yards with the rear sight at a certain setting. You would divide your sight radius (distance from rear to front sight. IE 28.5 inches into the inches at 50 yards 50X36= 1800 / 28.5=63.16. Now you are 6 inches low so 6/63.16=.095 higher sight at least.
