Obviously fluid dynamics and everything would be massive complicated, so I was wondering if instead a simpler system that kinda fudges the physics would work? For example, have a chance system where say every inch of penetration has a chance of curving/veering off its straight path calculated based on bullet speed and weight, and every say half inch a velocity check is calculated based off of a loss of velocity the further something penetrated, again based on weight and speed. For wound channels, have a line follow the trajectory of the bullet, and for certain type of ammo move the main cavity closer or further away from
the entry point. The main cavity could be a pre-modeled thing that changes in size and position accordingly. This way, there are still real physics based interactions, but its not a constant heavy fluid dynamics computation that would cook older machines. Any thoughts?

Some American Bullseye guns, like .38 special 1911s and the SW Model 52-1, for example, are chambered in .38 special, but can only fit wadcutter ammo with the projectile flush with the brass. I was wondering if it would be possible with the new ammo logic system to limit a gun to only use a specific type of ammo, or whether something like that would just have to be able to take any type of .38 special for it to function in the games logic.
