Here are some photos of the "Gun Box" and first carriage firing setup followed by a video of one of the shots.Box with identification to not turn it over and know where the muzzle is pointed. Next removing the cover and padded contents.After completing a slightly longer carriage, proportioned to the barrel I have made some bore depth measurements and marked them on the ram rod illustrating the various working depths that were machined and taken up by the charge load and ball shot for the remaining functional firing barrel length of shot for that charge load.
First the two carriages. The shorter would have been better for a carronade than a long gun.

Next is the ram rod to full machined depth of bore and charge, marked off. The diameter of the charge portion is smaller than that of the working bore. Depending upon the charge grain load that load extends past the charge depth into the full bore diameter, shortening up the barrel length for the ball shot travel.

I have skipped past the shot bore depth and charged depth, as well as face of ball shot to show all of those as marked on the rod which was being "extracted" with the shorter depths.View attachment 185810View attachment 185811
Here you see all of the depth marks and have to mentally "pull" the rod to your right, out of the muzzle to visualize the working depths in the bore.
Cannon under the black foam
Setting up at the firing range with the breach end view. Note the ram rod in the bore to assist in elevation aiming. Cardboard box to be sure that the first firing recoil is contained in addition to the carriage restraint hawser round the box ends and under sand bags. An additional sand bag for recoil stop if it travels farther than anticipated.
