@mjsdwash not an engineer. Just an old guy with 8 mostly functional fingers and both thumbs intact..
Btw, “just measure the air space” etc. will get you into trouble… the bullet is ALWAYS seated on the charge. There’s no other way to control “case volume” which is what we’re talking about and it is critical. You cannot for instance, load a maximum .300 WSM load (80grain case capacity) into a .308 case (56 grains case capacity) and then fire it in a .308 rifle of identical make to your .300 Short Magnum. Even if it will fit into the case, internal case volume is critical and a very small change has huge impact.
BTW, 10-15k is quite adequate pressure to scare the crap out of me… it’s been a while but I believe the HE grenades fired from M79 operated under 15k.
the folks at modern muzzleloaders can explain all of this much better than I can. It’s interesting stuff and I remember back in the day much time and money spent on development of caseless rifles and ammunition for military use. There are some important advantages to the technology.
