I understand the formula, I am using: target size in inches(95.5)/observed size=range. My question is, how do you measure tenths and hundredths of an MOA in a scope? 1.1 or 1.2 may be doable but a 1/100 measurement is what I need to know how to do. For instance, an 18 inch target observed at 1.76 MOA results in 975 yards while 1.72 observed MOA results in 1000 yards. 975 and 1000 are quite different even when shooting a 300 Win Mag at that distance. With a 300 WM, 208 AMAX at MV 2840 fps; 975 yards shows a drop of 226 inches while 1000 yards shows a drop of 244 inches. A clear miss with a very small error of 4/100 on the front end. I use an NP-R1 reticle. I am brand new to range estimation so any and all help is very welcome.
