My guess is that these shells are probably near 10k psi, but I may be off..

Any knowledge and or opinions?

Be careful with some older polywads. I bought a flat that apparently had no powder in them. They had enough charge in them to push the wad to the end of the barrels. They must have had issues because they replaced them right away. No issues after that.
