Adjusting for windage?

[Catfish]

I have a drop and wind drift chart on my long range guns. About any program will work for figureing drop as you should field check all of them befor you hunt with them. Wind drift is an art more than a science. I carry a wind meter, but tells me only the the wind speed where I am standing and I have seen 4 flags in 100 yards all pointing in different directions. Long range shooting takes a good rifle scope that track accurately, a range finder, a wind meter, accurate rifle and practice. High BC bullets, heave for caliber bullets are a big plus but you will need a barrel with a faster than normal twist to stablize them.
