[QUOTE="Hugnot, post: 2345465, member: 115658"] Agree ^, the Berger ballistic calculator appears to limit environmental stuff to temperature & elevation (altitude) and it appears to use the values shown in the table below to derive trajectories. As shown by BlackTail30 and other observations environmental considerations are sort of negligible like less than 1/2 MOA at ranges of 600 yards using extreme comparisons (Rocky Mountains vs. south east USA). Light air would affect bullet stability by increasing Sg values making bullets fly better by reducing drag & flattening trajectories. The Hornady 4DOF calculator accepts all usual environmental items. [/QUOTE]
