Having shot this gun at several rounds of skeet before embarking on this upgrade project the present restrictions of .011/.018 are much too tight for its main purpose. Thus far, I have to believe Shotgunjones suggestion of .003/.007 to be about right, but perhaps a little too loose for the other uses I may have for the gun---that is the very reason I am considering a screw-in choke system.

I have not experienced the fouling and additional cleaning of screw-in chokes that another poster has alluded to, is this a real problem with all screw-in systems or can it be attributed to a specific brand of chokes or specific brand of reloading components?

Doesn't anybody like screw-ins?
