I've seen a few Darne French double barrel guns chambered for the 24 gauge. The thing that turned me off was the lack of affordable ammunition (Fiocci was the only maker I knew of).

Beautiful guns for woodcock but certainly an oddity. I have enough troubles getting non-toxic loads for vintage 12 bores that are manufacturer loaded. (in my socialist state you can't use hand-load non-tox, only factory non-tox)

In my state we have to use non-toxic on state lands for dove and woodcock will surely be next. Then private land non-tox requirements.

In the grand scheme of things, the noose is tightening on us legislatively and that is probably why I was curious to own a 24 gauge but was hesitant to jump in with two feet.
