Billy, my shooting partner has one, and it is a pleasure to shoot. We haven't cast the chamber yet, so I don't have any particulars. Using gun show reloads with cast bullets at .379 he gets 1.5 to 2 inch groups at 100 yds with the peep sights.
I assume they are getting the barrels from Marlin, someone will correct me if they have different information. After shooting some med-heavy loads from the 45-70, it is a joy to pick yp the 38-55 and give your shoulder a break.
