Super Magnum V1
A physics model that makes the magnum:
1.  Have a recoil twice that of the rocket launcher and,
2.  The bullets are as powerful as a rocket.  No explosion, however :P
The magnum is more like a sniper rifle now.

This is a physics model, not a script.
P.S. If you are wondering where my other uploads went, it seems nobody likes them. 
Plus, they were the original property of Treellama.  This is the only one that I really made.  Oh well.
