So I set about creating a firearm. The thing I'm annoyed about is the fact that the magazine, when dropped for reloading, spins around and bounces a lot. Most of the time, it appears to float just above the terrain. I've been changing offsets and mass to see if it helps, but it doesn't seem to. What is going on?

Spriteoffset?
Doesn't that decide where the center of mass is n all?

Yup, definitely the magazine's sprite offset.
I once created the same problem in UniTec and had to change all of them. Fun times.

Ok, thanks.
