Drilling brass, some grades don't like been cut and they nibble your bit or the the bit bites the brass. Sacrifice a drill bit and file the business end down to make the rake negative.
The bar stock or round was pretty drill friendly and I couldn't get a new(ish) bit to bite, if I'd got a bottle adapter or something I probably couldn't get two rotations before it gets stuck in the work.
