   If you use a denser gauss bullet, I recommend you also increase the
barrel length to balance things a bit.  I've been using 0.1*Pi*r^3, and
barrels 2.5 times longer.

   Probably not worth the trouble, but if you want to be more complex
in deriving the mass of the bullet, here are some materials to choose
from:

bullet mass = df * Pi * r^3

   df    material
  ---------------
  0.02   glass
  0.06   iron/steel
  0.08   lead, crystaliron
  0.10   lead with a tungsten core (something like what the
         original gauss rounds were described as being)
  0.12   superdense
  0.16   tungsten, depleted uranium, gold (for cybermen :)


   For the magazine battery, I use the battery table from section 8
rather than the method used in the design sequence.

   Here's a handy table based on the section 8 battery table, in units
more useful for small applications:

Storage: how many Joules of energy stored per kg of battery
Power:   standard power output per kg of batter, in Watts
Cost:    credits per kg.  If it outputs power at a higher rate than its
         standard rate, the cost is increased:

         req/std output   Cost
         --------------------
         3125 - 15625     x25
          625 -  3125     x16
          125 -   625     x9
           25 -   125     x4
            5 -    25     x2
