HEy Paul,
There are no regulations on what your arrowhead is made of, or the size. Hell, you can even used barbed points.
I live up here in N. Ga and I had a small doe walk up a ridge toward me 2 days ago, but she saw or smelled me and trotted off. Been seeing lots of squirrels, but haven't had many shot opportunities because they're usually high in the trees eating nuts. It'll be another month before the leaves start falling...that's when the squirrel hunting gets good. I honestly don't bother chasing deer up here where I live....the deer hunting sux big time, so I spend my time chasing squirrels.
