Made a range trip today to chronograph some .357 loads. I ran three different loads through a 2 1/2" model 66-1, a 4" 686, a 4" Python, a 6" 19-3, and a 5" 627-5. The 13.5 grain 2400 load with a 158 grain SWC shot just fine in all guns, but I was a little disappointed with the extreme spread of my light loads of 231 and the same 158 grain SWC. Need to investigate this as it has always been a good load accuracy-wise.
