I'm sure Redhawk1 has already got his name on the waiting list for one. He'll no doubt come telling us how mild the recoil really is and I'm sure he'll get better groups than they mentioned. He really needs a new white tail gun anyway those bullets from the .500 S&W likely aren't reaching the far side of them any more.
When I first started shooting the .357 those 158s at 1550 fps were the standard fare for it. In the S&W 19 6" I used then they stung the hand quite a bit with the factory checkered grips. They also did what they were supposed to when they hit whatever ya shot at. I suspect that they still will iffen ya load to that level but you sure can't buy them at that level anymore.
Your a funny guy Graybeard.

I have seen that a long time ago, it is never going to be a production gun. It is illegal to own one. It is larger than the 50 caliber legal limit.
No the 500 Mag is all I need, as a matter of fact, most of the handguns I have bought lately are less powerful than the 500 Mag.
Now I have found loads in the 500 Mag, that are just to much for even me.. So I have no intrest in the 825 Magnum.
