.84 Rifle Barrel?

[Tacksman45]

Hi everyone, I am wondering how thick a swamped .84 caliber rifle would need to be at the breech and the waist? What twist rate would work best for this size bore?

Thanks!

The waist would have to be a minimum of 1.070. That would give you a .100 wall thickness to the grove depth if the rifling is .015 deep.
.840+.030+.200=1.070
Bore+grove depth+total wall thickness.
The breech and muzzle in my opinion should be a minimum of 1.300. and the muzzle at 1.150

What are you going to do with a monster like that?

That's what I was wondering, maybe a short barreled Jager?
