If the gun was only going to be used for quail and/or woodcock I'd say leave it be and adjust patterns by loads. But, for sporting clays I'd have Briley thin walls put in it. I have had that done by them and have, or have had, three guns that use them. No downside, IMO, except a minor aesthetic one. Possibly, Briley would make you tubes without the notches if you are willing to pay extra. You can use a choke tube tightener/remover that is a long tapered cone on a T-handle which grips the inside of the choke tube, and tightens or removes it by friction. If Briley would agree to make you tubes like that I believe they would also supply you with a suitable wrench.
