[QUOTE="Greyfox, post: 2350079, member: 10291"] The whole premise behind the “professionals” claim of a 100 yard zero is the effect of atmospheric conditions difference between a 100 yard and 200 yard zero. For my load of over a dozen years( 3000FPS/g7BC .32) the drop diffetence between a 100 yard zero and a 200 yard zero is 1.1 MOA. This does not change using at least a half a dozen different ballistic calculators with atmospherics ranging from sea level to 9000 ft and temperature ranging from 20-85F. Whether zeroed at 100 or 200 yards, that 1.1 MOA difference in elevation and actual POI is consistent to at least 1200 yards(my max hunting range) given I have accurately accounted for range and atmospheric conditions. When I set my zero, whether it is 100 or 200 yards, I will confirm the POI at [B]both[/B] distances. If using a 200 yard zero, I will set my scopes zero stop to allow a 100 yard check.. This serves as a rifle/load/form check as much as as a zero check. Given the aforementioned, my choice of a 200 yard zero for LRH is a function of convenience and confirmation. Using a 200 yard zero, my elevation adjustments are easy to remember, 1MOA increments for each 50 yards to 400 yards which is 4MOA. A supplemental, and exact 200 yard zero gives me high confidence. Regardless of all opinions on the subject, for over a decade,I have taken dozens of varmints and game animals from 500-1200 yards using either 100 or 200 yard scope zeros with no difference in results. On the other hand, setting a 100 yard scope zero exclusively for the tactical competition sports makes for easy match communication since a 100 yard zero is common practice amongst the shooters and spotters.
