We'll have to agree to disagree on the usefulness of the study, I'm afraid. I think pointing out this kind of data is exactly the type of thing that will encourage other studies to dig deeper on a topic. It seems to make it easier for other groups to perform studies after a possible link has already been established since it saves them legwork.

I doubt any NRA endorsed ranges or the military would allow independent studies of this nature to be done. But it sure would be nice.
