I have been thinking about "swaging" some copper jacket 9.3 bullets, not sure I'll even do that though.
I have a 9.3x74R "imp" that I came up with and then never wrung it out. I was thinking about coming up with a good 250 grain bullet and shoot a deer or two with it.
You can see the std. 9.3x74R compared to my "improved" case, in this picture,
