I prefer to set my scope cold bore shots for my farthest average shot and set my zero at 100yd for the distance. For instance my .243 is set 1.5 high at 100 puts It on at 200 and still with in kill zone from 250-300. The below is my ruger American .243 with a leupold 3x9x50 at 200 yards shooting .95 grain hornady precision hunters. I always sight in off sand bags with 5 shot groups. I do not like vises. Sorry don’t know as much technical description as many on here and there is a wealth of knowledge on this forum.
