Best I can do is about .08 for a cast boolit and .03 for a primer. Maybe .02 for powder, and effectively nothing for .45 acp brass that can be re-used a number of times.
That puts me at .15 per round. Since you are undercutting that by a significant margin, I'm guessing you are either casting your own boolits or stealing primers and/or powder.
I am not dedicated enough to cast my own boolits, and I'm not smart enough to steal primers or powder.
I'm pretty happy with .15 per round of .45 acp.
