Dan:
Thanks for the update, all we need now is a length measurement of the
piston and a length measurement of the protruding portion of the Pi3
pistol. I offer a possible explanation, until such a measurement is available.

"o and that the piston weighs 77#, and is about 21" inches in diameter."
"........about a 3/4 inch steel plate (think big garbage weight)"
I just can't seem to agree with that.......

Now look at the bottom photo on page 2. That is the "sliding piston"that weighs 77#, and that is not "about a 3/4 inch steel plate."

Look at page 1. The upper photo shows the front and the back sides of the "floating piston." The piston appears to be at least 12" long and must be a ball-buster to remove after firing a torpedo, and also after reloading another torpedo, stuffing it back in the tube behind the torpedo. I can't believe that a 3/4 inch plate would weigh 77#.
We have to allow for the length of this piston, add it to the length of
whatever torpedo (G7a, G7e, or TV) that is being loaded, allow for the length of the pistol (Pi3).
This all has to add up to no more than 297.5 inches, right?
You said the torpedo tube is less than or equal to 297.5 inches. I estimate that the piston is close to 12 inches long. You state that the torpedo in this thread is 282.5 in. Add both 282.5" for the torpedo and
12" for the piston's length. Subtact this total, 270.5, from the length of the
tube, 279.5" and that leaves 9" for the length of the Pi3 pistol, right?
I hope we can agree on this confusing discussion.
Have a nice day,
