8 x 56R Mannlicher Ammo, for the straight pull M95 is rimmed. 8 x 57 is not. You cannot make 8 x 56 from 8 x 57.
Hornady is making ammo for this and many other milsurp calibres. However, a company in the US, called Graf and Sons, has the exclusive distributorship for this ammo. Grafs does not ship to Canada, but they do have dealers up here. The two that I have dealt with are Raynorshine and BC Redneck. They have ammunition, ready to go, or they have reloading components, like brass and bullets.
dies are made by Lee, and I bought a set at Wholesale sports for $31.99
Dosing is spot on.
