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.
......................................................... 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.
Craig, now I see where you are coming from. Good arguments on both sides.
So now my question: What pressure is max for a Ruger .44m, and why wouldn't it be very similar to the Ruger .45; both use same frames. Is it the small difference in sidewall thickness of the cylinder?
