I've got some old 6.5 Carcono rounds that look kinda like those, got a whole lot of bullet sticking out of the case. Cool find!!
If they're carcano dimensions, youd probably be able to trade them into something more useful.Cool yes, but I have no use for them. Can't even guess at an age.
They are for the 6.5x53mm Mannlicher Rimmed. Also known as the Dutch Mannlicher cartridge, intended for use in the Geweer M.95 (the standard issue rifle for the KNIL in the Dutch East Indies).
An issue of American Rifleman 1954 mentions that Norma used to supply small quantities of 156Gr soft point bullets to the Dutch for loading 6.5x53mmR ammunition, which would be supplied to KNIL units that were stationed in the remote outposts of the Dutch East Indies. These cartridges would be used for defense against Indonesian tigers, as well as for shooting wild game to supplement camp rations.To answer the Carcano question: Many Carcano (all?) bores were a little oversized. I think .268 instead of .264. At one point, Hornady made "special" 6.5mm bullets just for the Carcano.
I think Hunter Habib is correct. They would also work in the 6.5X54 Mannlicher, which should be 160 grains, but what's 4 grains amongst friends?.
That was my thought too.I've got some old 6.5 Carcono rounds that look kinda like those, got a whole lot of bullet sticking out of the case. Cool find!!
I think the only option you have now John; you have to locate and purchase a vintage 6.5x53, 54, 55, or 57. That is the only logical thing to do.
