[QUOTE="bigngreen, post: 940528, member: 13632"] That calculator won't tell you how much of the total wind drift is coming from what range. You need to use a calculator that has the ability to use multiple wind velocity and directions. You'll find the larger portion of the total wind drift comes early, while the bullet is slowed at the longer range it does not have the time of flight to affect the trajectory. Take the 338 Terminator at 1500 yards pushing a 300gr OTM at 3198 fps, 10 mph wind from 9 O'clock. At 1500 yards you'll have a total wind drift of 81.4 inches so breaking it down into three 500 yard wind increments the first 500 yards contributes 38.4 inches to the total, the second 500 yards contributes 30 inches and the final 500 yards only contributes 13 inches to the total inches.
