I found a very accurate 38 Special load for my 77/357, by accident. No longer having a firearm chambered for 38 Spl., I figured I'd just burn up the two 20 round boxes of Speer 38 Special 125 grain Gold Dot HP's that I had left over. To my surprise, the first couple of 3 shot groups that I fired went a bit under 1.5" at 100 yards. I also tried them in my Marlin 1984CSS and they were superbly accurate in that gun. The groups were about the same size in the Marlin. It has open sights and my 77/357 has a 4x Leupold FX-II. Sometimes my old eyes and ghost ring receiver sights amaze me.
