Not that I have any heretofore unheard-of ballistic ideas, but I have a few things nagging me that I want to explore further. As this will be totally new territory for me, I would like to do some research first on the process of developing a wildcat cartridge. Anyone have any suggested reading on the subject?
For the most part I intend to reform existing cartridges by necking up or down and changing the shoulder angle/profile. Any suggestions on manipulating the brass in this manner? Would I be best served by custom machining a sizing die for each iteration, or is there another, simpler way?
