[QUOTE="RegionRat, post: 3093126, member: 57231"] In general, book values for ballistic coefficients are only used for estimates to get started. Anything serious requires actual testing in context since barrels can affect bullet drag and in turn the BC. My comment applies to climate and to windage, not just elevation/drop, so testing wind drift ahead of anything important and in as many different conditions is my advice. [/QUOTE]
