The chokes seem to be about full and 3/4 going by measurements and patterns. I will try some other ammo first to see how they go ,but I,m thinking of getting the chokes opened up a bit anyway to something like 1/4 and 3/4 or 1/4 and 1/2 ,so if new designed forcing cones will improve patterns with field loads ,then I would look into it while the gun was at the smith. But only if they do make a real difference.
