Thread: choke issues

I've got and issue the chokes in my pumpy. The top of the chokes bore doesn't sit flush with the top of the barrels bore, this is all chokes. Anyone had this issue? I've taken it to several gun shops and a gun smith. 1 shop said don't use, 1 said its mint shoot away and the smith was 50/50, he said worst case scenario a wad may catch the choke a tear it out or the muzzle will slip apart. I tried to take photos but none would come out clearly.
