Knock down power some range results
Sometimes ballistics testing can get too complicated and there are so many variables when it comes to testing a bullets performance that people really have to look at the results under realistic conditions and and realize that getting a hit is more important than which caliber, but when you compare hit to hit, there are differences in performances. I’ve seen ballistic results where 9mm ball ammo was said to have hit with the same energy that a 45acp had, but I have seen multiple times that steel plates would not go down as frequently with 9mm ball ammo. There were times when we heard hits and nothing would drop.
Now that so many criminals are getting a hold of body armor, bullet penetration is coming more of an issue. Even for those that are service over seas, 9mm ball ammo doesn’t penetrate a suicide bomber vest. M855 is not very good for soft targets but against body armor it is. We’ve been selling more Wilson Combat magazines to troops doing security detail because in their opinion 45acp worked better on soft targets and M855 was still necessary for penetration against suicide bombers and taking on cars.
