It seems foolish to push the round beyond its safety margin.
The safety margin is about gun it's being launched from rather than the cartridge itself. The .45 Colt is still evolving from its blackpowder roots and the weaker SAA and the like revolvers it was originally chambered in.
With the strong revolvers such as the Ruger, Freedom Arms and such, loads for it can and have been developed to its potential.
They Ruger Only
loads you find in the load manuals are set for the strength parameters of the Blackhawk. The Redhawk and Super Redhawk are even much stronger.
