The "fly-in-the-works" is Old Elmer Keiths data. It isnt going to take long for people to start trying to duplicate his 44 Special data in special run guns. It is one thing for Buffalo Bore to get 1050 fps out of their loads, given their engineering expertise, not to mention insurance. If you think there are idiots out there trying to find the "real upper limit of the 357 Magnum', wait till that crowd gets hold of Lipseys 44 Specials.
The question is how strong are these guns built on 357 frames? There are so many Ruger models and frame sizes out there, that I am not sure that I trust Ruger Loads in anything but the 3 screw Blackhawks, first New Model Blackhawks and Old Vaqueros. The one thing that I do know is that my New Model Super Blackhawk is a real 44 Magnum. Still, a smaller, lighter 44 Special is awful tempting, particularly the Bisley.
All good points. Unfortunatly, you can't teach good or common sense in school. If you want a .44 mag get what you want, and use it as you please. Not a one up, but I have seen a Super Blackhawk with an upturned topstrap, and two piece cylinder, with many pieces of both missing. Hopefully no innocent partys are injured when Darwin gets some excersize.
