HalfaDouble,
I handload for 8x57IR, IRS, 8x57R (360), and 8x72R. The cartridges are not necked as the 8x57R (360) would be (9.3x72R cases are sometimes used for 8x57R (360) however). They would more likely be 8x72R loaded in 9.3x72R cases, than 8x57R (360), but they don't seem to have enough taper to have been sized to 8mm. On reflection, the cast bullets might be 9mm Makarov bullets. They are the correct diameter but at 95 grains, they are too light. I have tried the Makarov bullet in 9.3x72R plinking loads, but the accuracy was not satisfactory. I believe the inaccuracy is because they are short enough to tip before entering the rifling.
