Go buy an X frame, why max out a caliber?The gun might be able to handle it, but why would you?

Probably the same reason for the 12gauge from hell. .44 mag factory loads are boring.The gun might be able to handle it, but why would you?

The REAL benefit of magnum rounds is sending heavier bullets faster, not lighter bullets. A 45+p with a 300+ grain bullet will go nose to tail through anything but the largest african game. Why do you need that same bullet to go faster?

They shoot pretty good too!

And penetrate like a freight train.

Those loads are basically the reason why I had this Bisley Super Blackhawk rebuilt with an oversized six shot cylinder.

SAAMI Proof Load pressures vary according to the standard pressure set for the cartridge. For cartridges of 21,000 psi or greater the Proof Load is Minimum 130%, Maximum 140%. Therefore the 44 Magnum Maximum Proof Load is 51,500psi. In comparison, the 454 Casull Maximum Proof Load is 93,500 psi. One could reason that IF the Redhawk 44 Mag is built on the same frame, with the same cylinder as the 454 Casull you should be able to safely shoot 63,000 psi loads out of it. But I doubt that Ruger proofs 44 Mag Redhawks at 454 pressures, and I doubt that they blow up guns to see what they'll take (nor would they ever publish that data if they did), so anybody who might try this is far into uncharted territory.Proof loads are doubled if I'm not mistaken. That's a lot more than 50k from a 454. The 44 magnum can handle +p+ loads in a redhawk for the simple reason that a .429 has a lot more metal than a .452. You can get a 454 cylinder put in a 45 redhawk and it shoots just fine. The super redhawk cylinders are much tougher metal than the standard redhawks so, it's the cylinder you need to worry about, not the frame.

Do you really think Buffalo Bore would produce ammo that is a danger to the guns? This path is well beaten, even if folks haven't heard of it before now....I doubt that they blow up guns to see what they'll take (nor would they ever publish that data if they did), so anybody who might try this is far into uncharted territory.

You are, indeed, mistaken.

The minimum and maximum average Definitive Proof Pressures are computed as follows:•The Minimum Average Definitive Proof Pressure is calculated by multiplying the Maximum Probable Lot Mean (MPLM) service pressure by the appropriate proof multiplier listed in Table 1 (SAMMI Velocity and pressure data - https://saami.org/wp-content/upload...FP-and-R-Approved-2015-12-14-Posting-Copy.pdf ) and rounding UP to the nearest multiple of 500 psi.•

The Maximum Average Definitive Proof Pressure is calculated by multiplying the Maximum Probable Lot Mean (MPLM) service pressure by the appropriate proof multiplier listed in Table 1 and rounding DOWN to the nearest multiple of 500 psi.•

The Maximum Proof Extreme Variation (EV) is calculated by multiplying the Proof Standard Deviation (which in the case of Centerfire Pistol & Revolver is equal to the Service Standard Deviation) by the constant 5.16(5)) and rounding UP to the next 100 psi.•

The Minimum Proof Individual (MPI) pressure is positioned three standard deviations (proof) below the Minimum Average Definitive Proof Pressure, with the calculated value being rounded DOWN to the next multiple of 100 psi.
