Hi. I responded on the question page but I didn’t want it to seem like I didn’t respond to this, so I’m saying the same thing here. 
Are your moving objects that collide both owned by the same system? In order to get good physics, the colliding moveable objects should be owned by the same system. Typically this is the server.
If your objects are not owned by the same system, you won’t get too good of collisions but I don’t think I’ve ever had them fly apart from each other at a higher speed. But I’ve also personally never played with MaxDepenetrationVelocity too much.
Does the default MaxDepenetrationVelocity setting work for your scenario?
