Just a guess, but I'd say 80,000 to 90,000.......I know S&W proofed their .500 Mag to 90,000.

Don't proof loads go 50% over the standard ? If so the standard load would be 60,000 psi !!

Everyone knows about the Freedom Arms line of handguns and how beautiful but expensive they are, well finally Ruger came out with one in the heavy duty Super Redhawk. Ruger came up with a new steel especially for this gun and cartridge. The 410 series of stainless steel that they use in the Redhawk just wasn�t up to the strength level that they needed for proof testing the .454 Casull. Read that correctly...PROOF TESTING! The 410 series steel WOULD handle the STANDARD .454 pressures just not the proof loads of 93,500 psi. Don�t tell me the Redhawk isn�t tough! I don�t know the exact name of this new steel but it sure seems to work well. With a load of 35.0 gr of H-110 behind a 310gr WLNGC for 1700fps and groups under an inch at 25 yds, I would say they got it right.



That got my attention....
