a REAL Co-axial

[Hydra]

Ok well Co-Axial means the barrel is inside the chamber right? Well in the real world Co-Axial means that there is another barrel on the same axis as the main barrel.
eg On a tank, there is the main turret, but on the side of the turret barrel there is a machine gun. Since the machine gun is mounted on the turret, wherever the turret points the machine gun points in the same direction.
Why can't this be done with a spud gun? See pic

Not strictly true. In tanks, co-axial means the guns fire along the same axis, meaning where the main gun is pointing, the machine gun points. In reality though, they are firing along parrallel axis.

In the sense of a co-axial spudgun, the barrel and the chamber are along the same central axis, making it trult co-axial in the proper sense of the word.

It's pretty much the same as dual barrels, except more pointless

There is no point in having two barrels really, IMO I would never ever bother. Why? Because you waste power so you can shoot two objects at a slower speed.


There's just no point, unless you can afford to waste the power, go ahead. But it'll still be a hassle.

Thats why you get a larger chamber...But its just a theory.

It has been done lots, tough generally a better way of doing this is either sabboting all the ammo into one bigger barrel, or just ramming 2 things down the same smaller barrel, one on top of the other, avoiding the unnecessary increase in barrel volume.

It's just being technical over the word 'coaxial'.

[BigGrib]

First off you are being too picky over the word co-axial. Second you use the tank analogy but your drawing makes no sense what so ever. In the tank analogy both the tank main gun and the machine gun that is mounted on the same axis are capable of firing independently of each other. Your design both barrels fire when the one and only chamber fires, unless you separated them with a ball valve or something, which would just be pointless. So if, based on your interpretation of the word co-axial, you were to make a real co-axial gun you would have to make two guns and bolt them together, which is still pointless.

Take a coaxial cable as an example. Its a wire inside of a mesh wire.
