Well, if you put any stock in the latest report from the FBI there is rough parity. In fact, this latest report states a preference for 9mm over .45. They argue the ballistics are similar and that, in fact, 9mm has an advantage because it is cheaper, carries more rounds, and has less recoil.
Don’t shoot the messenger. I carry .45 in the winter and 9mm in the summer.
No, no.
Your argument absolutely holds water.
A .45 is 8 +1 standard mag or 10 +1 Wilson mag.
Definitely bigger holes, more cavitation, especially with quick follow on shots, closely grouped.
You definitely have superior fire power but, your load out suffers compared to a 9mm, for the reasons you pointed out.
I also prefer .308 in M1A but, again, bigger holes and short comings compared to a .223/.556, which holds more rounds standard, weighs a whole lot less as does a full load out of 180-220 rounds.
typical AR has 20 round mags and will deliver twice as many rounds before I reload, if I don’t drop from exhaustion of carrying a similar load out.
My mags are steel compared to polymer mags and 10 rounds of .308 weigh more than 20 rounds 223/556.
for both my preferences I pay horrible compared to the 9mm&AR dudes.
But, my theory is shoot a man with a big bullet and be done with it, as well my hope is to be 500+ yards away....
like that’ll happen.
