Does anyone make 9.3x57 brass from 8x57 or .3-06 brass? The Redding form and trim die for this cartridge is very expensive. I would think that a standard 8x57 case could be run through a 9.3x57 full length sizing die and thus be formed in one pass, but I could be wrong. I don't have 9.3x57 rifle, but I am thinking about getting one. How do you who reload for it form your brass? jpattersonnh, feel free to chime in on this one.

I use Hornady New Dimension Dies for 9.3x57. The expander die is designed to neck up easily. I use Norma brass for this caliber. It is not cheap at about $1.00 per case. But it lasts a long time. I have not formed any 9.3 from 8mm as I really don't need to. It is not a caliber that you take out and shoot 200 rounds in a day. 232gr bullets suck. I have not tried 250gr. 270grJSP, 285grGCCL and 286gr Partitions all shoot great. W/ IMR4064 it has very mild recoil, even at max loads.

If you try it, look into anealing the necks first. I form 8mm from .270 and after anealing, it works great. No anealing = split necks
