Wouldn't best caliber for deer go under hunting anyway?
It seems no matter which way you split it, there's going to be an x variable that can fit between. Some forums have an AR only section, which makes the most sense to me, simply because the AR is the one most people seem to love or hate, promote or complain about. But with ARs you get AKs, ACRs, the whole shebang...and well its just complicated. Semi's and everything else seems the best, but people don't post in the right forums anyway. Optic reviews in the rifle section, bullet comparisons in the rifle section, etc.
Freedom's just a word. If I'm gonna die for a word, my word is jello...
