Yes, I see plenty of 20 bores here in the U.K. although the 12 is the most popular. Quite a few use the popular Beretta O/U 20's. What you won't see is anyone using 20's with 3" ammunition. British side by side 20's are light weight guns for firing a standard load of 13/16th. ounce. Anyone wanting to fire more than 1 ounce goes to a 12 bore. You might get some of the Beretta users loading up with 1 ounce loads for driven pheasant or something. I think that any 3" 20 coming from Europe will mainly be for the American market. Lagopus.....
