I do not recall a "Single" person here recommending to go out & "BUY" shells having a higher pressure than a gun was intended to fire, whether of the same or longer length. I did not omit that part of Burrard but you very conveniently keep omitting the part you don't agree with. That's fine, OK by me, but I don't feel I have given out any un-safe info. As I understand it the reason for changing from an "Ounce" proof to a "Pressure" proof was because of the situation you mentioned where a 1¼oz "Low velocity/standard pressure" was quite acceptable for firing in a "Normal" 2½" gun proofed @ 1 1/8oz. Many did not recognize this & thought it not with-in proof parameters. A similar circumstance was the changing of "Not-for-Ball" to choke. The change allowed shooters to "Think-for-Themselves" & realize a ball was quite acceptable as long as it was small enough to go through the choke. If you were to "MEASURE" all the fired shells made since the introduction of the fold crimp, & sold in the British trade in boxes marked "For use in 2½" chambers" or whatever is normal, I truly suspect you would be ABSOLUTELY FLABBERGASTED at just how mny of them were in fact longer than the chamber they were marked to fire in. You simply can't seem to understand we are not talking here of reading boxes, but putting up "Identical" loads in empty hulls by reloading. No one is recommending firing those loads made for higher proofed guns in a lesser gun.
