A sound Damascus barreled gun with proper wall thickness can handle just about any moderate load you want to put through it. JMHO, but anything below 9000psi would be safe.
The question should be what approved pressures are you looking for. There is no written rule, but more so what you feel comfortable with. Many guys like 7500psi, others 8 to 9000psi, and some don't care so long as it's not more than 10 to 11,000psi. The higher pressure loads usually mean more recoil and that worries many for fear of cracking the stock, not the barrels bursting.
So, I would say just find a mild to low pressure load you have components for and have at it. Good luck.
