MRC...You're a better man than I...I've tried a lightweight with .357...
first shot was perfect...2nd and 3rd had so much flinch that they would have been useless.
The 140 gr Silvertips were not all that bad. You could buy the Silvertip bullets back then and I hand loaded them about half way between a 38 +P and 357 velocity and they shoot good.
I have a Mod 60 stainless with the best DA trigger job I have ever pulled. I shot it a lot and decided to develop a 357 low flash load. I used a 125 gr bullet and 8 grains of bullseye which was max. It shot terrific with that load. When I got the Scandium 357, I started shooting that load in it and it shot really well also. After a range session, I went home to clean the Scandium pistol and the end of the titanium cylinder had actually flame cut from the gases blowing past the cylinder end and the forcing cone.
I sent it back to Smith and Wesson and they fixed it, no questions asked. When I got it back, I called up Smith's hand loading Tech Guy and talked to him about the load. First he admonished me for using that fast of burning powder in a 357 magnum load and I explained that it was a "book load" and how well it shot in the Model 60. We talked later and he actually tried the load in his 60 and agreed it was a great shooting load. Just don't shoot it in a titanium gun as you will melt it.
