I believe it was in the early to mid 1960s that a couple of women were doing quite well in competitive collegiate marksmanship, and a number of quite scholarly analyses popped up "proving" that the typical "female body structure" was better adapted to some kinds of shooting competition than the usual male.

While these bits of wisdom appeared mostly in the shooting sports publications, at least a few of them made it into some medical journals.

It was all quite wise and wonderful, and I think a number of people really believed much of it - at the time.

With good equipment, good instruction, peak physical conditioning, and sufficient practice, I doubt that there is a significant "sex-related" difference between what shooters of the various sexes can do.
