I've always wondered why 9mm has an advantage over .38 special. I can understand that most factory load vs. factory load, 9mm is probably hotter than the typical .38 as it has always been a high-pressure round, but what about reloading? Both use more or less the same bullet, but the .38 has a much bigger case behind it, which to me says it could be hand-loaded to levels way hotter than the best that 9mm could dish out. Is it a matter of gun limitations, rather than cartridge limitations? As in the typical autolaoder can handle a super hot 9mm load better than the typical revolver can handle a super hot .38?
