Ok , rifled tubes for 12 ga. guns are easy to come by . Not so for the 20 ga. , 28 ga.or really any other ga. but 12 ga. . Two guns i would like a tube for is a 20 ga. or a 28 ga . An idea for a 20 ga. would be to take a rifled bbl. and cut and thread it int tube length sections . We have a local gunsmith that makes tubes ( I have not approched him yet ) the inside dia of both bbl and bbl that the tubes come from would need to work/match . The 28 would be more difficult as i don't know of a riffled bbl. so if possible a rifled blank would need to be found .
WHY ? Well for years now i have had a rifle sighted smooth bore bbl. that i had threaded for rem chokes and use mod,XXf and rifled tubes for turkey and deer . The mod shoots foster slugs well , the XXF shoots 000 buck well and #4 turkey loads while the rifled tube shoots sabots well out to 100 or so yards . I could add a tube for small game if needed . This is the gun and combo of tubes that rides in my work truck incase i get a chance to hunt after work , during work or need a gun for soical events .If one added a bbl for sporting clays it would make a nice travel gun and raise little concern .
Any ideas wher 20 ga. or 28 ga. rifled tubes can be found to fit a browning O/U ? or other guns
thanks for any ideas .
