If 100fps doesn't make any difference why does one millimeter?
Because area is a square function of bore radius. When you increase bore diameter from 9mm to 10mm, you don't increase the projectile area by 11.1%, you increase it by 11.1%
squared , or slightly over 23%. Bigger projectile area translates to bigger hole through the target's organs, larger surface area through which the kinetic energy is transferred to the target's organs, higher velocity obtainable, all factors being equal, for the chamber pressure achieved.won't
The 9mm is a "driller"? With FMJ bullets, I guess maybe it is. It won't meet the FBI criterion for penetration (two layers of 3/4" marine-grade plywood, covered outside with multiple layers denim. After traversing the plywood and denim, the projectile must penetrate some set depth into ballistic gel. I don't know if the 9mm in FMJ trim made the grade or not. To the best of my knowledge none of the expanding point loads available have, even when loaded right up to the pressure limit. The .40
S&W, loaded to max, makes the grade with a little to spare. The .45 ACP in FMJ ball (not target ammo, not overloaded Buffalo Bore ammo) at 850 f/s, traversed all barriers and came to rest in the ballistic gel well past minimum distance. The 9x19 didn't seem to be much of a "DRILLER" in those tests. It's actual performance belies its reputation, it would seem.
And dream on, they will never reissue the 1911 again.
"Never" is a long time. The elite forces in Iraq and Afghanistan started requesting .45s and M14s (and GETTING them) within the first year of conflict, and I've heard nothing to lead me to believe that the demand for them by the individual operator has decreased.
And really, how important is a handgun in the overall strategy of combat?
Gee, I dunno, one Air Force Forward Air Controller on a radio can bring down worlds of ordnance on the bad guys. He's likely to be working alongside any combination of elite force units, and I suspect a .45 ACP will keep him alive at close quarters better than any wonder-nine you can name. One HOPES that his carbine is within reach, but if not, then his sidearm ought to be one without a history of stoppage failures as prolific as the 9x19 seems to have racked up.
Armed forces are becoming smaller in number, and their training times and expenses are both increasing. I'm not sure on how much money it takes to fully train one Navy S.E.A.L. team member, one Force-Recon Marine, or one Green Beret, but it would not surprise me to find out that it is in excess of $1 Million per man. ALL of these personnel can act in a way that is pivotal to the outcome of an engagement. I want them armed with ANYTHING we can afford to give them if they want it.
But I do admit I don't keep up all that much with what the military is doing.
Well, thanks for imparting all that "expertise".
It has no bearing on my life.
<shrug> Maybe, maybe not...
