Improved projectile design means that both 9mm and 45 ACP essentially make full use of their available kinetic energy. This has mostly (though not entirely) closed the gap between them in terms of performance, as they were never that far off in terms of energy potential. The fatter round just made better use of said energy in FMJ form.
At the end of the day, you get at best 30-50% more tissue disruption from the 45 ACP, at the cost of significantly increased recoil, increased ammo weight, and decreased gun capacity.
Ironically, that improved performance in FMJ also comes at the expense of making HPs less consistent. I was surprised seeing that result, but I guess there isn't a single caliber that's the best at everything.
Already been working with 9mm, 12 gauge, 5.56, .22 magnum and we are looking into .380
What is with the no love for .45 - Good lord, this is a Trump board - get with the program :-)
