I got my start in the hammergun world with the Husqvarna Model 20's & 17's built on the Lefaucheux (underlever) action. Stout, good handling guns with 2 1/2 inch chambers & usually choked full & fuller. They have plenty of metal for a good gunsmith to lengthen the chambers. Simpson's stock of Huskys has been well picked over , but there are usually some on Gunbroker. Once you get use to the underlever action their nice inexpensive guns.
Indeed, EVERYONE, thanks for your posts.
