Just revisited GS Custom's site and two 'new' DIY tools for helping with stuck cases which appear to be easily made.
I haven't made them, only just read about them but they seem good to me. Twist rate tool could be made with brass/bronze wire if wished I suppose.
Wounding theory interesting. I use gs custom bullets and find them good - no lead fragments obviously, no copper fragments or bullets recovered - go straight through, but then all bullets work well at some point and fail at others.
Here is an url for GS custom bullets http://gscustom.co.za/
Go to useful stuff and have a look at @shooting holes in wounding theory.
Have a look and see what you think, I'm not a ballistics expert but it seems sound to me. No doubt someone will be able so shoot holes in his article!
