I have the same dilema Tentman, I bought a type M in 8x51 Kurz several years ago. It came with about 60 primed resized 8x57 cases ready to load but I have not acquired any .318" bullets yet either. I'm not saying I have searched extensively, I did a brief search and have been firing other rifles. But I would like to load the cases I have and try hunting with that model M.
