Miller, the idea in proof was NOT that you would run your ammunition at "proof" level.
Well I reckon its a total lost cause to even try & discuss anything with someone too totally Ignorant to understand anything they read. I of course did not in any way even imply that a gun should be shot with the proof load. In fact some several pages back (you can go back & seek it out if you care to) I mentioned that a gun intend "For" 9k psi loads might be proofed @ 12K or even 15K psi. When I on several occasions mentioned it was important to know at what level a gun was proofed "FOR" that meant the service load, not the proof pressure.
If there may be 3 million people following this post Ted I think everyone but you understood what I was saying.
But let me say it just one more time @ spell it out very clear, just for you;
"IF" I want a gun proofed for 9,000 psi loads for use with smokeless powder & I want it proofed @ 50% higher pressure ie 13,500psi. Now it don't make a Rat's A**" what powder the proof house uses, Black, Green, Purple or Pink as long as the pressure reaches that 13.5K psi, they can then stamp it as being proofed "For" smokeless powder "For" a 9K psi service load.
Proof houses very early on realized it was not really desirable to stamp the "Proof Powder" on the bbl as there were a few folks out there too ignorant to understand just what this meant, so standardized smokeless proof marks were adopted, that is by everyone EXCEPT the FRENCH, it took them a while longer to catch on.
Now if a proof house decided to use a fine grain black powder & the (proof) load produced that desired 13.5k psi pressure then they could (& in some cases indeed did), stamp that barrel as having a "Smokeless Powder Proof" suitable for use with a 9K psi load of smokeless powder. Its all really quite simple, what's important is what the barrel is proofed "For", not what its proofed with.
