I use what I learned reading Jack O’Connor’s method as a kids. Sight in a 25. It’ll make most rifles 3”s high at 100. Shoot again at 100 to confirm it’s sighted in 3”s high at 100. Rifle will shoot point-blank-range (PBR) out to about 260-300 depending on the caliber. PBR means you hold on your normal aim point to roughly 300-350, caliber dependent, before making aiming adjustments.
PBR is how the Army sights in its rifles.
