Vic,
The barrel in my 9x57 is not the best in the world, so I quickly switched to jacketed bullets for my hand loads. When I was playing around with cast bullets,they were Lyman 358318(200 gr) and 358318(250 gr).I intended to try cast pistol bullets, but never did. I tried the common, for the time powders(Unique,Red Dot,4198,4895) but now I would use one of the 5744s.If the faster powders are used,a filler may be helpful, as would sizing the bullets a couple thousanths over groove dia.In my experience, the groove dia. is more often .358 than .354-356 that is usually cited.
Mike
