It's hard to come up with data when there almost isn't any. I must note that I shoot these out of a Gen4 Glock 21 with a KKM 4-port compensated barrel, which is right at 5" long. Although I have a few 200gr Gold Dots lying around, I mainly use 200gr XTPs. But with Power Pistol, my max load is 11.3gr for a muzzle velocity of just over 1,350 fps. I wouldn't shoot such a load in the stock G21 barrel.
Here is one link on some Super data:
"There is a principle which is a bar against all information, which is a proof against all argument, and which cannot fail to keep a man in everlasting ignorance – that principle is condemnation before investigation."
