To ALL,
I belong to "a Wildfowling site" in the UK/EU & several of my "worldwideweird friends" are shooting 10, 8, 6 and 4 bore SxS over there for ducks/geese with EXCELLENT results.
(At least one "Wildfowler" from Dublin is shooting a 2bore SxS with 44" tubes. = 28#.)
Note: If any reader/member has a SxS 4/6/8 bore flinter/percussion that they want to dispose of, I can QUICKLY find you a British buyer.
(Fyi, I'm a "poor boy" on a "gentleman sportsman's" site. - At least one of our members has a PAIR of custom-made 6 bore SxS with extra 8/10/12/16 bore weight-matched tubes for each. = I don't even want to know what that set cost.)
yours, satx
