Contemplating the purchase of a sxs for Sporting Clays. I presently shoot a Grant Side Lever Hammer gun for fun style matches - no money or trophies. Looking at a couple of options to acquire another suitable hammerless to give the Grant some rest. A pristine Cogswell & Harrison Konor (mid 50's) or a 1903 Westley Richards mid grade, quality restocked. Both are mid 7 pounds and similar choking. Probably refit with Briley Thin Walls. Any sense of quality/choice on these. Leaning to the Konor. Thanks.
