Does anyone here have experience in swaging the base/head on cartridge cases? I'm looking for data regarding brass springback, mouth-first versus base-first swaging, resulting cartridge elongation, friction using steel versus carbide, etc. The engineering texts I have don't have much data.
This seems to be a subject that suffers from a lack of available information. Despite my research, not much information seems to exist on this subject here or elsewhere on the web. I have a copy of Nonte's book coming so I'm hoping there will be some there.
