the Buffalo Bore low flash/recoil 125grn .357 Magnum goes about 1350 fps. Does this still keep up with such loads like the 145 grn Winchester Silvertip going 1300 fps?
Winchester lies. BB is right on. But if you look at the BB full power loads nothing can top that in terms of energy.
I carry an SP101 3" with their LSWCHP in .38 spl+P I clocked this round with my chrono and it created more energy than Winchester White Box .357 Mag 125gr JHP.
You gotta test em out and find what you like personally. They are all very lethal. No one can tell you what the "best" is, since it's different for everyone.
