Bill,
Twenty some years ago I got to meet old Ellwood Epps,...sort of a legend around these parts, he had already sold his store and was running a mail order business,..I guess he was selling old ammo to collectors, and more than a few guns that he had hanging from the rafters of his high ceiling ,...he grabbed a long pole with a hook at the end of it and brought down a big sidelock English double and said this is what you want for ducks!....if you've never shot ducks with a ten you're missing out on some real shooting.
As luck would have it I later ended up with that gun and shot it for years,..still have it, put a lot of lead and Bismuth reloads through it and made some wonderful shots on big Canadas, then one day on a rainy field shoot a bit of mud got in to the right muzzle and well you know the rest ,..the shot sounded funny and after the goose came down I noticed a piece the size of my small finger nail missing from the muzzle and a 1" crack that ran straight back, 32" is now 30",....and no chokes.
So I have been looking for a replacement for some time and now I've found it,....if it all goes according to plan It will be coming out west with me this fall,.....Geese look out!
