For those of you who are skeptical of the strength differences between the different 45 Colt revolvers on the market, here are some articles for you to read:

http://www.sixguns.com/range/454_super_redhawk.htm
http://www.realguns.com/archives/119.htm
http://archives.gunsandammo.com/cont...-45-colt-loads
The bottom line with all these articles is that the Colt SAA and clones are put in a category together with the S&W Mod. 25 to fire ammunition not above 14000 psi. All Ruger 45 Colt revolvers other than the new small frame Vaqueros (a Colt SAA clone) are safe with up to 32000 psi loads.
That sounds stronger to me. If it doesn't to you, then proceed at your own risk.
