Nothing WRONG with 16 ga., Wolfgang; I simply find 20 ga. much more versatile
in the US: lighter weight, and with 3"" chambers, plenty bird coverage for all but
large Ducks. In the US, 16 ga. is passé, I'm afraid, tho' it USED to be popular here
50 years or more ago.

Where would I look for a decent, european, used sxs hard gun case?
