"Sabotless" Semi-Automatic Shotgun Concept

Unread postAuthor: jackssmirkingrevenge » Sat Feb 23, 2019 9:03 am

An idle thought that is basically the unholy marriage of a nailgun and paintball marker:

The benefit is that it will fire whatever fits in the barrel and it doesn't need to be airtight, indeed it could be fed though a hopper of shot of whatever size doesn't fall though the detents at the breech. The disadvantage is that the projectile can only go as fast as the piston, meaning that arresting it would be a significant engineering challenge for something with decent ballistic performance.

Potential for quiet launching of very heavy projectiles

Indeed, noise abatement is one of the consequences of allowing the gasses room to expand before exiting to the atmosphere.
