I have a No 4 Savage with a milled rear sight. I have a good 100 yrd zero on it using HXP ball ammo. I lent it to a friend to shoot a 200 yard match, and he said that he had to come up about 12 clicks to get it zeroed at 200. Is this about right? How much does each "click" of the rear adjustment move the point of impact in minutes?, 1/4, 1/2? inquiring minds need to know. By the way, this is a very accurate rifle. Thanks for the help. Ken
