I have searched all over the internet and cannot find a ballistic coefficient of a lead cast, round nosed, 540 grain paper patch bullet. I am doing a physics project on the movie quigley down under. Anyone have any clue what a bullet of this shape and weight would roughly be? I am thnking around .2-.3? Thanks!

I only have one bullet handy, 540gr creedoor that has a b.c. of .401. That is a grease groove bullet. You need the b.c. for a paper patch bullet, which is higher due to the smooth sides. IIRC they are somewhere around .5-.52 depending on the nose profile.

Here is a calculator for BC. I wouldn't use it for modern rifle bullets but it will probably get you close enough for a BPCR bullet. Use the calculator on the left side of the page.
