Why anyone would worry about the hardness of their capping pin tip is beyond me. So long as sets off the cap, it's all good.
I grind or file 8mm coach bolts into a shape similar to shown by Pete Hall above. I treat them as fairly disposable and bend a couple on any capping session. I have the pin passing through a too-tight hole in a piece of welly rubber. I've never had one fly out using this method as the rubber grips the thread. If it did move, the rubber would slow it down and the rounded coach bolt head won't pierce me. I also use gloves, safety specs, ear-plugs and attempt to be out of the firing line just in case.
