.40 S&W is the least forgiving of any modern handgun cartridge in existence, for a number of reasons.

That statement struck me--not because it might not be true--but because it has become an accepted catechism: Beware reloading for the 40S&W as you would petting a Siamese cat. Bad things happen.
Then I thought about it a bit more. Why?
The 40S&W is not much more than a 9mm scaled near proportionally up to 10mm. Both use short/efficient cases, both operate at 35,000lb pressure standards, both do require the same attention to bullet seating depth/residual powder space, and both are shot out of the same family of similar autoloading pistol designs.
Yet the 9mm is "ho-hum" whereas the 40 is "Yikes !"
The only thing I can can think of is that reloading data
is all over the place, and the GAP/new reloaders tend to think of the 40 as a whomper-stomper and try to push the limits.
But the 40S&W loaded w/ similar attitude toward sensibility
ought to be no different than the 9mm.
Thoughts?
