Sod Wads? Hay Wads? Clay Wads? Wooden Wedges?

Could it warp or get out of round while cooling?

They apparently were not concerned about the possibility of the shot sticking in the bore, as they stated that loaded with the proper wadding that the shot could cool down completely without setting off the powder charge.  I assumed that they were still able to fire the shot out of the bore.  It probably caused increased wear on the bore. 

What they said was the heated shot when cooled would no longer fit in the bore.  I have never tried this, but I don't think they would have said this if it wasn't true.

Fit or fit in the bore?  Did they use smaller shot (before heating) to compensate for the heating?  Then again, the shot would likely increase in diameter by only about .050" for a 24 pounder shot at cherry red with windage of almost three times that (.145").  Shot diameter probably wasn't accurate within .050".

maybe they mean that it wouldnt have a proper fit to the bore as it was smaller after cooling and the scale was removed
I dont know , just a guess
