Why am I getting wildly inaccurate drag coefficients?

I made a simple CAD design of a very basic projectile with a tapered nose and cylindrical body, but whenever I run it through a simulation, I get diabolical forces and moments coefficients. For example, I have a drag coefficient of around 638,000 every time I try to run a simulation. I’ve linked the project here if you would like to take a look.

Hi,
