[QUOTE="Mikecr, post: 548923, member: 1521"] It was just a general example to illustrate my contention that wind drift is more about TLag than TOF. TOF is only a factor in determining TLag, and it's TLag that actually is a factor in wind drift. The decceleration that occurs due to drag causes the time lag which wind speed is applied to. Wind drift(in inches) is: 17.6*CrossWindSpeed(mph)*TLag(sec) TLag = TOF-TOFvac A higher BC bullet deccelerates at a lower rate than a lower BC bullet regardless of velocity(provided the BC relationships hold). So at any two points in flight, the higher BC bullet produces lower TLag, and is therefore less affected by crosswind between those points. It's a perspective that readers need to consider before concluding that they could reduce wind drift by going with lighter bullets at higher speeds. While they would reduce TOF, they could in the same move -increase TLag(due to higher drag) -increasing wind drift sensitivity. When wind drift is truly the focus of concern, so is TLag. [/QUOTE]
