Not the most brilliant news for a low power( comparatively ) Marauder…lol

Really? Do tell how exactly it is you draw this conclusion.

The hammer momentum is of course dependent on both mass and speed. With spring energy, and mass, you can get velocity, and then momentum. the momentum sets the dwell…all else being equal.

They…Read more
