The cannon arrived yesterday, but the manufacturer is sending a replacement since a flange at the barrel's breach end was bent so that the breach can't be locked. The 20-inch cannon is a "monster" as it weighs several times more than a high-powered rifle. Thus, the 10-gauge shells should create little recoil.

The recoil should be minimal since you're not shooting a projectile. Action-reaction thingy....

Yes. But then most/all civilian projectiles are measured in grains.

Sure ... a 16" AP round weighs 18,900,000 grains.

I can see why you leave your port fenders deployed while using the canon. One can almost see a shift to port in your wake.

That's wonderful Mark! How about some detail pictures of the loading and firing process? Who did you buy it from? Any plans to mount it on that pretty little dinghy of yours?

RBG Cannons.

No detailed photos on the loading process. ... One turns the breach (the fat end of the cannon) one-quarter turn counter-clockwise and then pulls it from the barrel. The shell is placed in the barrel. They breach is returned/secured to the barrel. The firing pin is cocked. Then one pulls on the lanyard. Boom.

No plans to mount on dinghy. A new mount would need to be designed/built.
