I have ability and time to cut my own monolitic bullets for my 8x57. I ve scalled down a known monolitic 338 design, and cut it on my small cnc lathe. Now, I ve used brass (designated Ms58 half hard here, I dont have full specs). I am worried is it OK to use it as a material for it, or should I use copper instead? Or some other type of brass, if I can find any. And from what I have read, in load development I should use similar charges for those kind of bullets-weight (and start up low and work my way up) and consider QL as a help tool.
