Does anyone shoot store bought ammo besides RST in their Damascus guns, like Gamebore?

Started using stamp about 1926, however the stamp is merely an indicator of pressures that Parker had been using for years .
No.
10,500 psi service loads , 13,500psi proof loads. TPS contains a table of Parker service and proof loads.
Parker did not distinguish between composite and fluid steel barrels for pressure loading.
Your 12 ga was intended to shoot as a standard load 1 1/8 oz, 3 dram ( or DRE) loads . A 3 DRE load will run 1150 to 1200 FPS. Stated maximum loads for 12s are 1 1/4 oz , 3 1/4 Dram , clearly a stout load.
I shoot Remington, Winchester , Federals , Fiocchi , RST . All off those companies make 1 oz 2 3/4 Dre loads and 1 1/8, 3dre loads.
