The idea that a small 9mm auto is ballistically the same as a small 357 wheel gun has been floating around and proven or disproven, depending on who you believe. Several of us shot some rounds over a chrono today out of a small 357 (LCR) and a small 9mm (G43) just to collect data. The chrono was dropping some shots which is why we don't have 5 readings for all the rounds tested. If we use the G43 with the HST rounds as our baseline, full power 357 loads out of the snubby deliver 16-22% more power than the 9mm. That's not a whole lot more given the downsides of trying to hold on to the 357, but it's not exactly "the same" if you like math. We did not have any 9mm +P to try, going to see if we can find some to see how it does vs. the Critical Defense in 357. I actually use 9mm CD, so I can chrono that as well.
