My Uncle has a nice old German (Sauer) sporting rifle chambered in 9X57 Mauser. He's had it for years and years and he's never shot it. I'm hoping to change that. I've aquired an old box of German made, 247 grain .355 round nose bullets. I've got a set of RCBS dies on the way, as well as 100 pieces of new 8X57 brass.
So.....
Is reforming the brass as simple as running it up into the 9X57 FL die?
Any suggestions for a mild starting load?
No need for anything more than that, I don't think this will be any more than an exercise in paper punching.
