I'm trying to identfy a cartridge I have. It appears to be a 8x57 mm. It is a rimmed case. It looks like the 8mm mauser, (8x57 rimless.) The markings on the case show 19 on one side, 16 on the the other, Vll on the bottom, and D,A, and possilby C on the top. Could anyone share with me exactly what I have. I'd really appreciate it.

Thanks,
Tim
