Gentlemen: I was cleaning up the disks today, and came across this figure which appeared in Parker Pages a few years ago. It shows that regardless what the guys in the grey flannel suits say, chamber pressure is simply a function of the length of the shot column.
Parkers are strong, they will take a lot of heavy loads without saying uncle. Along the way to uncle , chips will appear behind the tang, and the stock will begin to show some space along side the tang.
Remember that 80% of Parkers were made when 3/4 ounce was a twenty gauge load, 7/8 ounce a 16 ga load, 1 or 1 1/8 in a twelve, amd 1 1/4 ounce in a ten.

Best, Austin
