My load is only recommended for Ruger revolvers and Thomson Contenders because it is based on the higher pressure loads that were initially released by SAAMI for the original large frame Smiths.
The current limit for a 140 grain Sierra JHC bullet is 18.0 grains of H110 with a magnum pistol primer. My load is 0.5 grains below the original maximum loading of 19.6 grains of H110 at 19.1 grains with a magnum primer and a heavy crimp. Using this load in a lesser gun will rattle the side plates loose and possibly twist the frame. I have been using this load in my Ruger Security-Six for 45 years with no detectable wear anywhere. In the three year period that I competed in Hunter's Pistol Silhouette I fired over 30000 rounds in practice and competition. Add to that the extraneous trips plinking and hunting and the 40 or so years since then, the gun has had a lot of rounds through it. It has never seen a gunsmith and is still in time and shoots 1 inch average groups at 25 yards for me. I added sights that I made, and a grip that I bought, to the gun. I found out that plated cases split at the mouth from the crimp but haven't had problems with the brass cases.
I repeat that this load is for Rugers and Thompson Contenders only because it is above the now standard SAAMI pressures
