Bolt thrust is the pressure, times the area it is pushing back on, same as a piston in hydraulics. The actions ability to stand up to this pressure is a factor of the lug shear area (and contact), both bolt and receiver/extension and the tensile strength of the material they are made out of. You can model actions in different CAD software packages and run Finite Element Analysis on them and see which ones have the strength.
