The onion skin that I have is less than half that: closer to 0.0025" (It's 12 or 14 lb IIRC; have to find where I've hidden the box), while typing paper is about .004 (20 lb that I have; one source says 20 lb can be 0.038"-0.048" depending on how densely it was made). Onion skin does come in different weights, compositions (100% cotton rag is usually thought best for PP use), and densities, but I'm wondering if you're remembering what a full turn around the bullet adds to its diameter?

I think the idea behind the .301" bullet is to be sure the lead is fat enough for the rifling to slit the patch, though how it stays sharp enough over time, I don't know. Knives and scissors don't stay sharp cutting a lot of paper.
