[QUOTE="Dave King, post: 52015, member: 3"] Wind drift as I understand it: Time Of Flight (TOF) has a significant effect of wind drift. Example: 1300fps, 155grain .30 cal .5BC bullet, 10mph full value wind, TOF to 500 yards 1.377sec, wind drift 36.2 inches. 2600fps, 155grain .30 cal .5BC bullet, 10mph full value wind, TOF to 500 yards .708sec, wind drift 20.6 inches. another to be checked by anyone interested: Two bullets of different caliber (significantly different) with identical BC's. shot to the same distance in identical wind, theoretical result should equal essentially the same wind drift (disregarding sail area). When all else are equal weight has no effect on wind drift. [/QUOTE]
