[QUOTE="BrentM, post: 1981668, member: 61747"] I am really surprised people still use cosine and distance as the correction factor. Ballistic calculators use slope angle, distance, time of flight, atmospheric data, BC, etc to compute a shoot to correction. Rifleman rule of slope angle correction times distance is fine for short range and minute of deer but it is not precise enough for long range and small targets. [/QUOTE]
