I'm still trying to catch up on my blog reading, and Kurt pointed me to this online article which states, in the final paragraphs:
Ohio deer hunters can only have three bullets loaded at a time.
That's because wildlife studies find the more bullets hunters load at once, the more likely their guns will accidentally go off, with potentially deadly consequences.
On the one hand, I've never fired more shots than necessary for the kill when I've been hunting (and that's always been one shot, thankfully), despite the fact that I consistently fill the magazine whenever I load a weapon. On the other hand, my hunting buddy hunts with a lever-action .308, and he always works the lever and fires another shot without checking to see if his first shot was effective.
But notice that the article doesn't say that the studies indicate that more bullets means more shots (and my buddy doesn't ever shoot more than the three, and usually only two anyway). It says that more bullets make it more likely that the weapon will discharge accidentally.
I'd like to see that study, preferably in the company of the author(s). Then I'd have the opportunity to pistol-whip them when I discover the problem with the study.
Note for the humor-impaired: I don't even own a pistol right now, and I'm not particularly violence-prone, except for my quarry when I'm hunting.
