I know there is an article somewhere which has data specifically for the newer Colt SAA clones. I think it was in handloader magazine but I'm not sure which issue. I think they rated vintage colts at around 14000 psi and the clones at 19000 psi. However I'm still searching for that info. Does anyone have this data? Sure would appreciate it. I think it was in 2002.

This might be it:
