After playing quite a bit with the fluid simulator, I tried the body rigid and this is my first animation. Very simple one, one bullet and some stuffs to smash.
The blend (image) is not really well worked, I put my effort into the animation. I promise I will give you better stuff in the future, but I think this blend could be usefull for beginners.
Here it is :
You are right, I know what you mean, but if I had put the projectile only, it would have been too small for the animation. It is not realistic, I recon, but I did this blend just to get used to the rigid body simulation and also the animation (sound and composite). I hope it can help some beginners ;)
I do not know how well I call it in English but... the shoot dont fly all bullet, only projectile fly. Cartridge case is ejected from the side arms.
