My pinhole is a 4X5. One thing I've done to help make the pinhole more circular is turn a sewing needle into a drill. I take a micro-file (emeryboard would probably work too, but might take a bit longer) and file the tip of a sewing needle on both sides so that it's flat on either side. This makes a neat cutting edge. Then, I put the material I'm drilling through on a piece of hardwood (okay, I really just put it on the table, which is hardwood) and with gentle pressure, spin the needle between my fingers. If the material is substantially thick, I do both sides once the hole has made it through the metal, so that it lines up properly. This gives a bevel on each side, with a thin, sharp edge in the middle, which is good for pinholes. It does take a while, but it makes a nice pinhole, much nicer than simply punching through the material. Aluminum from soda cans works pretty well, as far as I can tell; I haven't been shooting much pinhole lately, but the initial results were nice.
