Anyone that wouldn't hesitate to own a 9mm K-frame or larger revolver but doesn't think a 38 Special can't surpass it at less pressure don't apparently know how to go about things. I wouldn't load it to 357 levels, but theres a a ton of "room" people just don't equate with the 38 for some reason.
Staying away from old school Winchester cases or new Remington cases helps. And "Blazer" cases may look like Federal or Speer cases, but they aren't.
FWIW, Sierra VI edition lists a 1,200 fps. 158gr. JACKETED load fired from a 5.6 inch barrel with 2400 and two other powders at 1,150. 170 gr loads clock 1,100. These are 38 +P rated loads, meaning they are under 20,000PSI and CUP, a long ways and a lot of safety margin compared to a 9mm that's been chambered in the same/similar revolvers.
Throw in lead slugs and the speeds with the same powder charges get quicker.....
Personally I think the 173 Keith or a 180 dual crimp LBT at 1100-1150 does a whole lot of work with a lot of accuracy and its on the heels of a 357 without as much fuss and way beyond the 9mm with far less pressure than either.
