"Looking for loads for a 6" .357 for use on called coyotes."
You don't say which model of revolver you have. I have found the 125 HPs like the Speer or Winchester work fine when started out at 1450 fps+. In the stouter revolvers such as old and new BHs, S&W L and N frames, Ruger Security Sixes and Freedom Arms, etc., you can very safely push the 125s to 1600 FPS+ out of the 6" barreled revolvers. I have a 6" Security Six that I worked up to the Max load of Bluedot as listed in Speer #11 with the 125 Winchester HP. It runs 1680 FPS in my Ruger. That was also the revolver Speer used developing the loads in the manual. I can assure you it is quite deadly on coyotes out to 70 yards (about the farthest I'm comfortable shooting at one with iron sights). That load does bark and snort a tudge and I found Pachmyer grips to work much better than the smaller, slicker factory wooden ones.
I use the same load for deer only with a 125 FP/xtp and it runs 1690 fps. Zero is the same for either load.
