How to make a 9mm match a 45 acp?
The answer is ------ It depends!!!!!!!
What do you want it to do?
Damage the same amount of tissue?
A deep driving bullet that opens to at least .45 in.
Stop an attacker?
Much different mechanics.
The way many stops happen is by nerve damage.[AKA PAIN]
The 45 causes more pain because it damages more nerves.
The most in skin, next muscle, a little in organs ,next to none in bone.
The 45 acp driver a .45 hole through all.
A 9mm starts at .355, then a controlled opening to max opening.
As the bullet is rotating at many 1000 rpm the largest opening pettel
will control the damage till the rotation slows down.
The 9mm will damage [touch] fewer nerves than the nonexpanding 45.
Less shock [AKA PAIN} but the expanding 9mm may damage more
tissue [AKA BLEEDING].
Pain convinces you to stop, bleeding make you faint.
This is why the 357 125gr SJHP remington load worked so well.
The speed at impact caused the nose to blow off [With in the first 1/2 in or so] the base ,now a WC of about 100gr , would continue on causing
a deep wound.
Pain AND bleeding.
To make a 9mm work like a 45, load it like a 357.......
