I shoot a savage model 12 in a .223 cal. and have it sited in at 4" high at 100yds. and about 5.5" low at 300yds. How can I figure how much drop there is at 400, 500, 600 yds. ? Not that I want to shoot yotes out that far, but the conversation came up yesterday while hunting and I couldn't answer, so I went out today and shot the rifle at 100 and 300 yds. Is there a simple formula for a person to use to get the general basics. I know there is a lot involved with it, but it would give me a rough idea. Thanks
