Bigcountry, Shooting squirrels with a bow is a blast. Take plenty of arrows and I would suggest using bludgen tips if you can. I went with field points and the little wire judo tips and lost at 12 bucks an arrow I figure I spent a hundred bucks! The black rubber tips look pretty cumbersome but they work like a charm and stop in a hurry.
Somebody correct me if I'm wrong, but was told that .38 special brass makes a great bludgen tip when glue'd on the end of the shaft. It would be cheap enough.
