Kind of curious...from what I have seen looking around...smoothbores, especially doubles are out of my price range. That said, would a .36 cal. be a good choice for both? I was thinking of a .32...but I saw a fellow at the range the other week with one...the range rod looked to be about the size of a soda straw....looked kinda weak to me. As far as a .40 goes...for squirrel...I would kinda like to eat the critter...not use whats left of him for a biology class. Any replys as always am thanking in advance.
