WoodsyAl, yep, something to pass the time and learn something.
Nothing wrong with that at all. I agree with the other comments that for 150 yard hunting it's pretty much irrelevant, but for a lot of us (myself included) the study of making rifles shoot well is just as interesting, if not more so, than the hunt itself. Personally I've become much more of a shooter and reloader than a hunter; I still hunt as well but find myself thinking of it as a rifle test too.
