16 is pretty much dead in the water in NA.

The lead shot ban and not much available in 16 bore hundering it. Along with that, the 16 has never been really popular here. A bunch of guys I know, like 28's , however, for grouse hunting.

A few have them but 12's and 20's are the most popular, with 10 bores finding favour amongst some recoil-resistant water fowl hunters.

I had a 16 bore Husky SXS for a while - nice gun, with the right barrel, straight rifled.

It shot IMP Cylinder patterns out of the right barrel & full choke patterns out of the left, modified choked barrel.

It was a GREAT grouse gun.
