[QUOTE="med358-boise, post: 2593257, member: 123832"] On a base charge in the 80s, I would be using a .6 increment. But set that aside, I think your answer is 81.3. The POI is very consistent between 81.1 thru 81.5, so the answer is the mid point 81.3. I think people get way too worked up over extreme spread. Take your ES of 25 for 81.1 and call it 26; therefore your maximum likley variance is 13 fps. 13 fps on a base of 2900 equates to a change in drop of 2.4 inches at 1000 yards for the bullet. If your distance ranging is off by 4 yards you have a greater drop variance. [/QUOTE]
