Thanks guys !!
Want to try two more?
These are center fire, rimmed, with no head stamp. The rim is tapered like the 7.62x57R except thar these taper almost to a sharp edge.
The first has a 0.534" rim, 1.77" case length, 2.287" OAL, straight taper, 0.372 bullet. It looks like a 38-40 Remington-Hepburn or a 38-35 Stevens or 38 Bullard but I don’t have any dimensions for those.
Second is a tapered case with a very long shoulder and a long neck. The rim is 0.524", 1.842" case length, 2.247" OAL, 0.308 bullet. The case dia. at the base is 0.455", slight taper for a dist of 0.78", a sharper taper for a dist of 0.45", then a neck, 333" and 0.46 long.
