Prior to punching/cutting I slobber on the end to moisten it up and wait a moment. But for some reason I occasionally get a busted up head. What's up with that?

By no means an expert, but it looks like you used a punch. What I've found is (1) if you punch too fast, and don't rotate the punch while pushing, or (2) the punch is dull it will split the foot. This has happened to me before.
I generally give a punch a back and forth (short) twist. I'll pay more attention next time and ensure I give it a good twist and less pressure.
It's a new punch that was a bit cheap. It's done well the few other times I've used it. How would one go about sharpening a punch? A file?
A small ignition file would work. Quicker and easier is a small grinding stone on a Dremell tool.Quote:

Exactly!! I use a 223 Remington for smaller rg and a 243 Winchester for larger. Then if I need a big hole I also have a 9mm Xikar. Just make sure and chamfer the brass so it is nice and sharp. Very easy to touch up if it gets a little dull.Quote:
