A little food for thought/reality check:

It was noted by Indy' that the 200gr Accubond drifted 21" at 600 in a 10mph crosswind.

For S&G, running the same bullet in a 300WinMag at 3000 fps MV, results in 18" of drift at 600 yds.

A whole 3" difference in drift between the lowly .308, and the mighty 300WinMag long distance critter-cruncher.

A guy has gotta be able to make a decent wind call, or be willing to pass, with either round.
