WebAug 9, 2024 · Yes. ballistics calculators start with time = 0 and distance = 0 at the muzzle, the sight height is the vertical distance between the centerline of the bore and the line of sight (center of scope) at that point. Since the angle between the scope and the bore is so small, it's good enough to just measure at the scope in whatever way it is easiest. WebJul 12, 2024 · The height of the observer's eyes; The atmospheric conditions. Obviously, a mountain range ⛰ five kilometers away would reduce your horizon by a lot. However, it's hard (read: impossible) to calculate this: we can only consider the height of the observer's eyes in our Earth's curvature calculations.

WebThe distance to target is 720 inches ( 20 yards ) and the sight radius is 6.25" ( typical milspec 1911 with fixed sights ) With these parameters it shows a needed correction of .013" So if it was shooting 1.5" high at 20 yards we would either have to lower the rear sight or raise the front sight by .013" WebBrownells bison roof pedestals

As for this method, just do the following: Get the measurement of your scope tube and divide it by 2. The scope tube is typically 1 inch or 30 mm. 1 inch is equal to 25.4mm, half of which is 12.7mm. WebApr 1, 2024 · ACOG BDCs are designed to be at a sight height of 2.7" and presumably the TA51 and other Trijicon mounts provide that height on in-spec M16 and M4. That's off bore, not height over rail. Again assuming milspec the (top of the) pic rail is 1.211" over boreline, so that is already 1.489," right?
