History of the .22 Tuba Cartridges:
These cartridges started out as a novelty, but they are now a working cartridge.
The two different 22 Tuba cartridges were designed, produced and have been fired in a special firearm by Zachary Weighman, a highly respected cartridge collector and wild-cater.
With the idea that these funnel shaped cartridges will force all the powder to be burn and vaporized long before they reach the rifling.
