Okay, so when I got home tonight I re-ran the calculations.
Here's what I put in:
10 mph cross wind,
Sierra 168 gr MK with 2550 fps muzzle velocity
Eley Tenex with 1085 fps muzzle velocity
Here's what I got.
For wind drift equal to 100 yards = 45 yards (let's call that 50 yd)
For wind drift equal to 600 yards = 330 yards (let's call that 300 yards)
For wind drift equal to 1000 yards = 615 yards (let's call that 600 yards)
So, like I said above, the distance scales at less than 3:1 and in fact it's only about 2:1.
Furthermore, have you ever even shot a 22 in a 10 mph cross wind at a target 600 yards away? No, I didn't think so. Me, either. Think about that, remeber they put almost all of them in the ten ring and many are X's, then shake the hand of the next long distance shooter you meet.
