Sort of continuation of another post. Anyway, I've got some old Paper shells like many. Remington, Winchester, Western etc. What pressures were these loads at ion's and ion's ago? Have to believe someone tests them years ago.

I'm sure that most were listed in LUP's and I don't think there is a conversion to PSI.

Depending upon your definition of ion (eon?), those loads will probably pressure test just about the same as current loads meeting SAAMI specs if your first eon is around 1940. If you are going back to 1900, they would probably test around 8000 in smokeless powders and a little less than that in blackpowder. Pressures are guage related to a certain extent so smaller guages might be a little higher. But the earlier comment about any data from them being in Lead Units of Pressure (LUP) and not directly convertible to psi per modern strain gage measurements. What is the point of the question?

How long in time is an ion? Even I'm not THAT old. I'm only a couple of eons, give or take an acre or two.

I once picked up a girl in chemistry class. I wrote a note that said, "I've had my ion you for an eon." But it didn't work out. We had opposite charges.

Send some to Whats his name and have them pressure tested for $5.00 each and then we will all know. My suspect is not far off what the current standards are. Currents are only a little higher than old times except for steel shot loads.

Guess that is eon. Wonder why spell check didn't get that one. Who is "whats his name"?

Tom Armbrust tried pressure testing some early 1900s shells and found the results to be inconsistent related to primer degradation and hardening of the fibre wads and cases (causing increased pressure.)

Guess that is eon. Wonder why spell check didn't get that one. Because "Ion" is a word, an electrically charged partical. Spell Check can only read your writing, not your mind as to how you intend using it.

Tut, if they're short shells, chances are they run around 1,000 psi lower service pressure than the current SAAMI standard. But, as noted above, those old paper shells can degrade over time. There was no industry standard prior to the advent of SAAMI (mid-20's I think), but all the gun makers proofed their guns; likewise ammo makers with their shells.
