bwanabobftw, I am not sure H&H would develop anything for the monies that I could put up. 😊😊

On a serious note, I am not sure what research and development is realy needed to rifle the choke of a set of .410 barrel. If a company like Boss (or H&H) is building a custom DR in 22H with a second set of .410 barrels, it seems that the cost of rifling the choke for the .410 barrels would be relatively minimum. Of course, those barrels would have to be regulated. But that would be a cool double rifle, Likely good for both quail and whitetail. Just my thoughts.
