Your old Sears Roebuck single shot is worth $50-$75 retail. Since it's probably 80-90 years old, you don't know how well it's been treated over it's life, so before you shoot it, let a gunsmith check it. If he says it's safe, you can use modern shells. Shot size and powder load varies by what you want are hunting, but avoid magnum loads and steel shot.
