Hunter Arms listed the Skeet Upland Special as having "Skeet Choke No. 1 right and No. 2 left." I believe the Winchester Model 21 WS 1 was .005 and WS 2 .015 for 12g. Could you lucky fellas with Skeet guns please post the gauge and constriction of your barrels, right and left? or e-mail me at revdoc2@cox.net? or come out to the 'Doubles in the Desert' shoot in Tucson March 1 and I'll measure for you Thanks to all!
