I’ve got a Grade 2 top lever 3 frame 10 gauge that at some point was sent to Belgium and fitted with a set of fluid steel barrels and 3 1/2” chambers . Barrels also have Briley screw ins
Anyway not to long after getting it at Hausemanns in June I made a trip to Greentop Sporting Goods in Glen Allen VA and bought some 10 gauge 3 1/2” slugs and buckshot . Unless I’m mistaken the four boxes cost me $100 and that’s for twenty rounds total .
