Chamber-Barrel position
The possibilities are limitless, but these are the most common ways to position the chamber and barrel:
- Linear or inline
- over/under
- co-axial
- "multiple tanks and Ts"
Like the setup used on the megah-launcher. However, the multiple bends results in slightly reduced flow. GGDT simulations typically don't show much improvement from the increased chamber volume.
Projectile delivery
The basic option. Projectile loads from the front, and reload time is quite slow. If there's any significant friction between the projectile and barrel, a ramrod must be used to push the projectile down the barrel.
- Union loading
A step up. Alows you to load the projectile from the breech, but requires alignment and twisting afterwards. A union can also hold a burst disk. Cam lever couplings are similiar to unions, but faster to open and close. They are usually rated for less pressure than unions.
Alows you to load a projectile from the breech (end of gun towards user). Mechanism and loading time varies by construction technique.
A tube holds the ammo, about around half a dozen balls. Upon firing, the balls are sucked one-by-one into the airflow, resulting in a tight grouping of balls fired a few dozen miliseconds apart. Suitable for large-caliber weaponry (has been tested with as large as tennis balls) Named after the late Bill Vogt, who came up with the design.
