I have to disagree with the best launch platform for a hunting 357 revolver. The redhawk was short lived here. I found the large frame 357 Blackhawks would take any load the case was capable of holding. I was able to assemble loads well above book loads in either one without any problems till the brass became the weak link.
The problem I had with the Redhawk, which is a fine gun in it's own right, but very bulky, leaves much to be desired for a hunting trigger in single action, which is all I use in hunting situations, and not nearly as nimble to carry and use.
The one thing none of the double actions can equal over the Blackhawk single action is, trigger pull! There is no finer single action trigger pull available than on the Blackhawks. all mine are under 2.5# and some closer to 2# or a tad under, with crisp no travel breaks. In my opinion,,, the Blackhawk as a hunting round in 357 is the Ultimate Launch platform!
I know some think double action could be needed if charged by a ??? bear???? or maybe a cougar??? Sorry my thinking is if I'm hunting in these enviornments where dangerous game could be a human threat, I wouldn't consider a 357 as worthy hunting gun in this enviornment, but then just maybe a clumsier, double action could be considered a better launch platform, but it sure wouldn't be in this caliber.
Lastly I have to question what what anyone calls hunting loads that thinks a 686 or even the beefier in my opinion GP-100 ,as being anywhere close to equal, to take the same heavy loads I assemble with 180 grain slugs to any Redhawk or Blackhawk,,, to think they are is just fantasy!
Now to the OP Buckey Bill, I would grab that Bisley, as I personally like the bisley over the standard single action grip frame, and this kinda hard to find at times in the 357 caliber. I was lucky enough to grab one of the even rarer 5.5" which is my favorite barrel length or close to it 6" being perfect, and in Stainless Steel. But was almost ready to grab the next blued Bisley I cam across when I stumbled into the 5.5" Stainless unfluted here. I have had excellent luck with my 180 grain Mihec Large Hollow point bullet weighing 172 grains as I cast it, driven to 1455 fps average, with under 1" 25 yards groups. This gun you are looking at would no doubt be capable of equaling this performance, and I believe it would be very difficult to ask much more out of a 357 cartridge without extending the barrel, as there is no advantage to extending the frame or cylinder for this cartridge. JMHO
Buy it, it won't last long, and many think it will be the best launch platform for a 357 hunting cartridge!
