This may be the best load for .38 Super, yet devised. If Unique is in short supply, AA#5, AA#7, and VV3N37 make excellent substitute propellants. Obviously, the load data will be different, but similar performance is entirely obtainable.
I'm not sure I agree with this. I'm not sure why velocity would be king, when lighter (and lightly constructed) projectiles tend to not always behave according to expectations, as velocities increase (especially in game-sized animal tissue). Personally, though the momenta of both loads would be the same, I'd far prefer to use a 145 gr. LSWC, launched at 1250 f/s, than a 125 gr. JHP at 1450 f/s.This is not a cast boolit so I'm not going with the bigger is better but velocity is king. 124gr.
