RECOILLESS CANNON CONCEPT
Then I thought and "oh, rifling."
Rifling means machine shop work, and I'm aiming to use relatively common drawn over mandrel steel pipe of large caliber... so I thought a bit and then-why not use a finned sabot? It's good enough for the M-1 Abrams 120mm smoothbore. So I came up with this-then I remembered the Foster shotgun slug is meant to be shot out of smoothbore shotguns-that would increase potential payload... at the expense of velocity, range and a more pronounced trajectory so I amended.
Other than that it's a recoilless cannon-not a rifle, this is a smoothbore. Slap some large DOM seamless pipe together, and yes you will need to machine a breechblock. This is a conceptual drawing and not meant to be an actual blueprint. You finish that but it's got to beat using that Civil War re-enactor's Parrot Rifle.
