My re-loading skills are fair, but I would not try to duplicate that load personally. I have wanted to buy that very load from Buffalo Bore. My Rugers (SP-101 & Security Six) would handle it, no problem. So too, undoubtedly, would my Model 19-4, but my 19-4 is my baby and I only fire in the 19-4 what I test in the Rugers first.
