RE: squirell hunting w/ bow
I would make up some flu-flu arrows (lots of different ways to do this) and get some blunt or hex heads. I've heard of guys using .38 shells on wooden arrows. A judo point could get messy. Flu-flu's will keep you from shooting an arrow 300 yards and safely allow some shots up in the trees. You can make one by putting some glue on the front tip of some feathers (4 or 5") putting them in your jig and then marking where the back end would be. After the front dries, glue the remaining feather and glue it to where the next arrow would have ended, maintaining the same helical direction. This will put a severe twist in the feathers and slow the arrow down at about 40 yards or more. You can also glue a feather on and twist it backwards, barber pole style, up the end of the shaft. Makes something that looks like a chimney sweep.
I prefer friedrather than ingravy. Squirrel was also used in the original Brunswick Stews. Check your local game regs first for legalities. Have fun.
