For those that have spent a lot of time at the pattern board ......... when is a 12 ga. choked excessive to the point of not patterning? Reason I question this is I saw a 12 ga. with a .729 bore dia. that has a .665 Turkey choke installed naturally with for lead shot only inscribed. That would be .64 of constriction. It would seem that would be excessive to say the least. I would think that if someone made the mistake of shooting steel in something like this it might take off the end of the barrel.
