Yeah, a long shot like that will be affected a lot by the wind. The range I belong to has target set-ups only at 100 and 200 yards. I mostly shoot at the 100 yard target where the wind is less of a factor. The wind drift is much more noticeable at 200 yards. I enjoy impressing fellow shooters who are using a scope on a modern rifle by shooting tight groups with a 99 year old M1917 with open sights. I've been reloading Hornady 150 gr FMJBT with 48 gr of Hodgdon BL-C (2) in .30-06 for the Winchester M1917 and the Remington 03-A3.
