Bruce, I'm not at all sure I agree with you about wind drift being equal for all bullets with the same BC. Certainly, it is a part of that, but so is simple inertia, and the .45s have a lot more of it.

I don't really see any upside to shooting a .40 at long range. I don't know why anyone would want to do it, other that was the only rifle available. I do see an upside to the .40s with silhouette.

Various people have campaigned .40s for long range and none have done consistently well with it. Some of those shooters were well established shooters also.

FWIW, the King of the .38s is unarguably Rick Moritz. Rick does not use a .38 for midrange, nor does he use a .40 for long range. There is a reason for that.
