RE: 38/55 caliber?
It's becoming pretty popular again as cowboy action shooting is reviving it...as it has several other older cartridges. The .38-55 is a GREAT deer rifle, debatably over powered for typical whitetails, but there's no such thing as too dead...it makes a great elk/moose rifle, and a pretty sweet bear rifle as well, the only problem with it is that it's not chambered in many guns, to my knowledge Marlin (owner of H&R and NEF) is the only firm that chambers ANYTHING for it, one a lever gun based on the 336 (336cowboy) and one a single shot (H&R target rifle)...If I didn't have the .45-70 counterparts to each of these (H&R buffalo classic and Marlin 1895cowboy), I'd buy one or the other, probably the Marlin 336Cowboy, put a glass on it and it'd make as good a hunting rifle as most bolt guns ever thought about being, let alone the value of being one of a kind!
