Dennis, once you buy the brass, about how much more is it to load for the 9.3 x 57 than a more standard caliber? I am guessing the bullets might be more??
It's mostly a matter of bullet cost -- there aren't any cheap 9.3 bullets, though the 270 Speer and 286 Hornady might be considered almost reasonable. I do wish Hornady had brought out a bullet more in the 250-275 gr range than 286 gr, but that's just me.
If someone made a good, cup and core bullet of about 265 gr weight that cost less than 30 cents apiece, it would help.
