Apparently the civilian version is the same as military @ 80,000 psi. SAAMI spec. Sig data shows it to have the bi-metal cases. https://en.wikipedia.org/wiki/.277_Fury
With loading dies one could roll their own from .308 cases but keep the pressure down to around 60,000 psi and call it a managed recoil load
