I worked over my ballistics simulatiom and fixed some errors. If the
drag coef is around .5 I don't get ranges arounnd 400 meters when
launced at 330 m/sec Mach 1, Terminal velocity is around 30 m/sec

What kind of range are you getting with your cannon?

I am thinking spin and dimples have got to be adding lift
