Also referred to as the M31 Hungarian and 8 x 56R Mannlicher this was an updated and more potent version of the original 8 x 50R Austrian round. It uses a non-standard 0.329″ diameter bullet, while sometimes standard 8mm bullets will work, generally the accuracy is poor. It is used in the straight-pull M95 rifle. This brass is packaged in lots of 20. Shipping weight is 295 g/20 cases.
