The basic question is whether or not to open up the chokes on an Iver Johnson Skeeter.

The gun is a 28 gauge, CCH, ejector with 28 inch barrels. All original. Chokes are IM and F as marked and also measure that way. Shot it for the first time at the Southern SxS.

I am guessing that fewer than 200 were made in 28 gauge and the CCH and the tight chokes may make it a one of a kind.

I would ideally prefer IC and M. But, am I violating a great gun in doing so?
