I have always reloaded with AA or Claybuster wads, and Never gave it much mind. When reading about a UK specific guns with recommended use of lead only with fiber wad. I asked myself why only fiber, and does anyone in the U.K. Shot plastic wads? I guess I am a little clueless of why the specific difference.

Maybe, the game keepers don,t want plastic wads laying all over the place. is there that big of a difference on how choke acts with plastic verses fiber.
