This is not a recommendation for a load but just simply a testament to the strength of ONE Model 36(no dash #). When I first started reloading in the late 60's I had a Ruger .357 and my Model 36. I had no .357 mag cases so I was loading mags on .38 cases, I guess you can see where this is going. I was loading a cast "Keith" 168gr SWC and wanted to try a "heavy" load for the snubby of 10 grs of 2400 behind that bullet. BTW that is a decent load for .38's at about the upper end of the .38 pressure range and 1000fps out of a 6" gun. Anyhow I loaded the snub up with 5 rounds and expected heavy recoil and I sure got it! I had instead mistakenly loaded 5 magnums with max loads of Herco powder (max at the time, now 2 grs over todays max listing!) and fired all five. That little 36 really bucked and roared but lucky for me it held together. The gun had no ill effects, no loose or sloppy cylinder, no excess end shake, nada. I have the gun today and carry Winchester +p 158 LSWHP's in it. Also since then it has fired at least 1000 rds of wadcutter and my standard "K" frame 158 rn load.
Again this is no recommendation, just a story about an inexperienced young reloader and a tough little Model 36 that survived his dumb mistake.
