Remington had a 22 based on the 510 series called a Rutledge and it was marked so on the barrel. I can't remember if it was Mossberg or Rem. that had a sort of thrower that attached to the barrel and it threw a small clay target that the shooter could trip. Someone also made a thrower that tossed Ritz type crackers. I thought it looked like fun, but never tried it. I have heard of guys tramping fields with these guns though and wingshooting grasshoppers.
