If you throw the .45 360 gr. cast bullet at the same 37,900 CUP's as the .44 uses, it would blow the .44 away in velocity. As someone has been saying over and over again and in different ways, physics is physics and doesn't change.
Yes, I've read the Linebaugh article too. I asked this same question when I read it. How is that relevant? It's quite the obvious statement but completely irrelevant unless you can run a six shot Ruger .45 at 37,900CUP. Which you can't (or shouldn't). All that matters is the pressure range acceptable for the gun's limitations. The .45 is restricted to 80% the .44's pressure. THAT has not changed and THAT makes all the difference.
The point being that the .45 does not actually run away from the .44Mag until it's chambered in a custom five-shot.
