The Win M92 clones, Win M94, Marlin M94, Colt Anaconda, and anything chambered in .454 Casull are fine with these loads. The original Ruger Vaqueros that were built on the Blackhawk frame were fine with high pressure loads but the newer smaller framed Vaqueros will not safely take them. Also, never use these loads in any Colt SAA or clone like the Beretta Stampede, Uberti Cattleman, etc.
