[QUOTE="JDD, post: 1633153, member: 102774"] In reference to the above copied data. It was correct for standard bullet profile of the period. 168 gr 175 grain match kings etc. The higher the bc the less impact temperature and air density will have but it is still there. You also need to factor in completing factors. You sight in at sea level at 90 degrees temp drops to 70 you will see the change . I. Use to see as much 3 moa change between day break ,or sunset come up for 500 yard rams then what I would need at noon time . on one occasion I saw a 5 Moa change. Sight in at your home range at 1000 feet at 70 degrees then drive up to 5000 feet to hunt it 50 degrees up that so you would think a 1 moa change due to temp. You would be wrong . Air density is much less up there and cause a competitive condition off setting the drag caused just by temperature and has to be factored in . [/QUOTE]
