Yes, sorry, I meant Directional Deformation. Insert a second one for the Y (vertical) direction so you can see how far the bullet has fallen due to gravity.

In Rigid Dynamics, under the Loads button is Remote Force which you can use with a + sign after you convert Pressure to Force and then with a - sign to use for the drag force.
