Interesting invention for sure. But as a black powder enthusiast I know traditional black powder fouls a barrel in short order making it harder to reload with each successive shot.
Being caseless means the projectile left behind fouling matter right where the next bullet loads. I doubt if it made it through the entire chain of bullets before it jammed as the breach would be quite dirty after a while.
In other words, I do not think it could be fired as fast as the trigger was pulled as the article asserts. Now if a bore brush were ran down the barrel between every few shots, then that would make a difference.
You cannot compare this to a machine gun that shoots cased bullets as the casing’s simply being in the breach keeps it clean enough so when ejected the next round can be easily placed by the mechanism.
I’ve worked with jammed projectiles in a black powder propellant muzzle loader. The round binds up quickly when the bore is fouled. I suspect this chain gun jammed also and was a serious reason why the weapon never became popular.
I stand corrected in my post #7.
After watching the video a few posts back, my theory does not hold water. The chain has it’s own chamber for each round meaning the bullet does not have to be pushed into any breach, thus it cannot jam.
So yes, it could be fired as often as the trigger is pulled.
