I don�t know if your computation can take into consideration, the shape of the cartridge itself.
Assuming, as most I�ve read does, that the cartridge is well adhered to the chamber walls at 10,000psi, a straight walled cartridge would inherently have less back thrust than a tapered cartridge thus imparting less force upon the breechblock for the majority of the pressure curve.
The OD / ID of the barrel shank and how much meat the action adds may be as important to consider in these smaller actions than the block design.
H&H also chambered at least one of these small �02 actions in 22 Savage HiPower. That has 40K + pressure and a very tapered case.
