I appreciate the replies. Here's a pic...
Finally got the picture to load.
That load is pretty much a duplication of the old .38-44 HD load, the precursor to the 357 Magnum, and should run about 100 fps or so slower than full power 357 Magnum.I shoot Buffalo Bore Outdoorsman loads through my 4” 10-5. Ballistically they are equivalent to mild 357 loads. No ill effects. I don’t need another model 10 but I’d gladly pay $400 for that gun
