[QUOTE="brant89, post: 2619590, member: 49553"] I understand what lag time is and how it is calculated, but wind drift is still not DIRECTLY related to TOF even though TOF is part of the lag time equation. You can fire a low BC bullet at a higher velocity for a decreased TOF but an INCREASED lag time due to the lower BC, and that lower BC bullet with a shorter TOF will still have more wind drift. Plugging in numbers from JBM (200 yards, 10mph crosswind): .284 195gr EOL @ 2700 MV = 1.8" wind drift , .232s TOF, .010 lag .224 50gr Match @ 3600 MV = 5.4" wind drift, .197s TOF, .030 lag Three times the lag time equals three times the wind drift, even though it's only 85% the TOF. Directly related to lag time, yes. Directly related to TOF, no. This example might be what [USER=1521]@Mikecr[/USER] was alluding to in his comment. [/QUOTE]
