I found this on a friend's property recently along with various relics. The place was a farm as early as the 1880s or '90s This 45-70 seems different thsn ones I used to have in cartridge collection, maybe it's the head having a raised center.... Was surprised to find something this big in Kansas where the biggest game is probably whitetail deer. And for once found a whole casing, most are half gone. Headstamp is W. R. A. CO. 45-70 - thanks in advance!
