Interesting couple of videos on reloading if times get tough.
But being the machinist that you are, I am sure you could make something beautiful and effective.I don't disagree, but this guy shows you what is possible. Would also be possible to reuse components from other unusable rounds to make useable loads using these techniques.
Id be more comfortable shooting my pistol than I would something cobbled together.
