I have a Win Hi Wall in 38/55 on the way, it is very similar to a Browning, which was made at the same time, 28" Tapered octagon with regular sights, scope mounts and rings, and a Marble's Peep mounted on the tang.
The owner had slugged the barrel and sent me pics, it will need a .377 bullet, which I already have the mold and molded up about 250 slugs that are .379. Should I size them or try a few first. When I get it in and get some pics we will post them. I have really come to love the.38/55 in the short time I have had one, a JES Marlin 336 that was bored, chambered, and rifled by him. I may have to use it hunting deer next year.
