You’ve got that completely backwards. .40 S&W is far more powerful than 10mm. And the FBI statistics back that up. Double blind testing has proven than 10mm lacks the necessary stopping power for defensive use which is why the FBI dropped it way back in the ‘70s.
I’m pretty much an expert on the caliber. Recommend you stop before you make yourself look silly.

I guess the Hornady Reloading manual is wrong, along with all of my other ones.
