I have carried for years while bowhunting, but I have a CPL.
I don't know why on earth I would want to 'double hunt' and scare away that monster buck with the crack of a .22 pistol (or whatever) in an attempt to take game. At first the regs seem silly, but practically speaking, just get a CPL and keep quiet in the tree. I'll be happier not hearing you or seeing your blaze orange.
That said, I think most of us have at one time or another have lobbed an arrow at a pesky squirrel.
