simailar to the blue bomber, if I were to construct my gun in a switchback type design to make it a little easier to wield (not to mention cooler looking, heh) how much power would be lost by the 180 bend and by the fact that the projectile isn't right at the mouth of the explosion.. any feedback will be greatly appreciated.. as I said before, I read through every page of the new and old forum.. but this is one question that I didn't really think was clearly answered

by adding more distance between the projectile and fuel, coupled wit the fact that you are "isolating" the projectile via the 180 degree bend, the fuel should combust more completely before accelerating the projectile. It is effectively a sort of "burst disk" mechanism

The effect probably won't affect performance at all, but I'm assuming that the CB ratio will need to be different for optimal performance. Plus if you don't obscure the area between the actual chamber and the projectile, the bend should act like part of the chamber. So don't forget to add this volume into your chamber measurments.
