I have an older American pigeon gun. Now don't start getting your panties in a twist just yet. She's a wonderful gun with a vent rib. The right barrel has a bore of .732 the last inch is .720 thickness of the metal is .052 the left barrel has a bore of .732 that choke tapers down to .690 barrel thickness is .060
To me someone has backbored this barrel maybe to clean up some pitting or they where onto plastic wads before anyone else was by 40 years LOL. When I compare the choking to other fixed chokes from the same maker something is not right. I'd like to get this issue addressed.
Does anyone know if I have enough metal to get thinwalls installed and if so would you have Briley or Teague do the job. This could turn out to be a wonderful clay gun and back up pigeon gun.
