Atomic rounds... very phallic, very sexy.

Nuclear tank rounds? Goodness sakes.

Naw, nuclear battleship rounds. Fin stabilized too; I just haven't built the sabot and railgun armature yet.
EDIT: And yes, that nose cone curve is from a real math equation: y=x^.75, resulting in a power law body. I chose .75 for the exponent based on literature implying it to be the optimum shape for a hypersonic projectile for minimum drag. Also made the boattail and fin leading edges the same shape.
My only real limitation with Graphcalc is I can't really control for the equivalent wedge or cone angle I want; hoping to find a factor (or equation to give me same) to accomplish this.
