And that the difference in expanded diameters among the different calibers is insignificant.
I'm very familiar with it. Here's what McPherson says:
On the first, the "correct target" is hidden and moving, and hitting is takes more than marksmanship.
On the last point, --well, it is listed last, but I would not use a .22, or a .32, for that matter.
The 147 grain PDX 1 9mm expands to an average of .54 inches, and the .40 165 grain load, to .6.
Yes, and that the increase in expanded diameter over prior premium loads in the Winchester PDX1 line has been proportionally much greater in 9mm than in the larger calibers.Have you learned that the same technology is also applied to larger cartridges???
And that the difference in expanded diameters among the different calibers is insignificant.
What does that mean? You may or may not hit what is important, and a lot of what determines you do is a matter of chance--which is improved by faster shooting.Shot placement is a given.
Getting killed by bears or cats due to a miss infinitely more likely than getting harmed in a self defense situation? Come now.True but the likelihood of encountering those consequences is infinitely more likely in hunting than self defense.
What in the world is that supposed to mean? You cannot penetrate tissue without destroying it.Penetration without tissue disruption is nearly useless.

The three primary components needed for effectiveness with handgun bullets are as follows and in order of importance. These are facts and are indisputable!
1. Bullet Placement - Hit the correct target and you will have better results than if you don't.
2. Bullet Penetration - The farther the bullet goes into the body, the more damage it will cause.
3. Bullet Diameter - The larger the hole the more permanent damage that is done to everything that is in the pathway of that bullet. A 1 inch in diameter hole will cause more permanent damage than a 1/2 inch hole. In other words, a .45 will cause a bigger diameter hole, hence more permanent damage, than a .22.
