Why Did It Split?

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 spent shell casing makes a decent punch!

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.
