Like most other newbies, I've come to this site looking for guidance in pushing my limits in long range shooting. I've lurked for quite a while and searched through lots of old posts. I am interested in setting up a rifle that will be used on deer, and long range practice. I hesitate to "qualify" long range as I have yet to shoot at any distances greater than 400 yds. My current rifle range is 300 yds, and I just learned of another near by range that goes out to 500m. Several years ago I was captain of my University's rifle team. Form, ie. trigger control, breathing, etc. will not be my issue. I see my biggest limiting factor being the wind. With that said, I am currenty looking at various chamberings in 7mm, .300, and .338. What I have not read in the usuall "7 WSM vs. .300 RUM" type of threads is discussion of "wind bucking". Is this because there is little difference, so it is a non-factor? Hypothetical situation, I have a 700 yd shot on a whitetail with a stiff cross wind. Is a 7mm 180g VLD going to be pushed of course more than the .338 300g pill? Thanks.
