[QUOTE="BrentM, post: 795756, member: 61747"] Most trainers address the affects of wind at the muzzle and down range. They break the range into 2 parts, for example: 1000 yard shot. 1st 500, 2nd 500. 1st- bullet flight time is less than 2nd, initial bullet push is X. 2nd- bullet fight time is more than the 1st, secondary push is Y. It is the component of both units of time, distance, and push that must be accounted for. If you shoot from a wind hide the wind may be zero until you hit 300 yards. From 300 to 1000 the wind is X. OR you could shoot from a wind prone spot, ie top of bare knob down, into a draw. From 0 to 300 wind is x, from 300 beyond it is zero. This is where experience and math helps a person understand the greatest affect of the wind. It is also the reason some people choose 250-300 grain bullets from large calibers with high BC's. Much less affect and much less understanding of overall wind affects. I will give an example of a recent shot at 1200 yards: wind was from the right to the left at 6 mph at shooter. At target the wind was 6 mph left to right. Both winds did come from back to front at about 45 degrees to line of bullet path. Here is the test question: would you shoot for zero wind since theory tells you they cancel each other? If not, what adjustment would you make for wind? [/QUOTE]
