[QUOTE="Bart B, post: 105292, member: 5302"] [ QUOTE ] These drops in inches are straight out of "Ultimate sniper" By major John L. Plaster.

Having worn out 4 barrels in 7.62mm NATO converted M1 Garands and a lot of the ammo was LC M118 Match (M2 173-gr. bullet), my zeros (I've always remembered them) were as follows at sea level for the M1NM rear sight having a bit more than 1 MOA per elevation click; one can calculate the bullet drop at each range from this data: 200 yards, 5 clicks up from the bottom (front post height changed to do this; 200 yard drop = 10 inches). 300 yards, 3 up from 200 yards, up 8 total. 600 yards, 12 up from 300 yards, up 20 total. 800 yards, 10 up from 600 yards, up 30 total. 900 yards, 6 up from 800 yards, up 36 total. 1000 yards, 7 up from 900 yards, up 43 total (that's about 440 inches of drop).
