The measurements in Drew's picture don't look like "blow-up" thicknesses. Back to the obstruction theory.

I asked the metallurgical engineer at METL who supervised one of my failure studies how much the wall thins with stretching before bursting and his answer was "not much".

So tell me, Doc. If it doesn't stretch "much", where does the extra steel come from that goes into creating the big bulge? Be specific, please.

Measure the thickness of an uninflated balloon's wall, then measure it after it is inflated. What do you think the results will be?

"Not much" in one's man's vernacular may well be enough to cause a rupture, in another's.

May God bless America and those who defend her.

People shoot old ammo or load ammo to low pressures, therefore, obstruction should not be ruled out.
I have simple rule if 12ga gun can't handle 1oz game load at about 1250fps or 7/8oz for 20ga I dont want to own it or to use it.
Classic guns are cheap now. Last one I looked at was keeper gun from Birmingham by English & Son (very prestigious shop from Bath Street). It had 28" imp cyl-mod barrels 2&3/4" chambers with 1&1/4oz proof, $500 plus tax.
