While I find this interesting, I have heard of more than one 6 shot super blackhawk that was blown up by shooting 5 shot high pressure 45 colt loads in the factory six shooter.
Still darned impressive what the supers will do.
Have heard of a number that were blown with heavy loads of the wrong powder. The 5 shot loading data I've seen will run 10-15,000 LB less pressure than what a case full of powder runs.
