A ....... It's really all about shot placement. Do it right the first time and you won't need a second time.
Now, an odd piece of advice that I was given. Use (or not) it as you see fit: First round is a ball like a 124gr NATO/+P and then your defense round. I'm not sure I agree, but I don't know that I disagree.
Thoughts?
Hey, thoughts I've got.
Just one example, the FBI Miami Shootout. Plenty of rounds fired by trained professional LE officers---that's why they called it the "Shoot Out", instead of the "FBI Textbook Felony Stop and Fast Demise of Maddix and Platt."
The issue of bullet placement gets discussed ad nauseum. Over and over and over again. What happens in real life shootings over and over and over again, is that things turn to crap, and oft mentioned bullet placement is less common on the street than on a gun forum. Not saying it isn't important, just that it's easier said than done.
No it is not ALL about shot placement.
Bullet selection in the caliber is also important, though secondary. The will to keep fighting is also important, and so is the use of tactics.
Been plenty of folks survive by getting behind something that stops bullets when their excellent range marksmanship is still back at the range during a real gunfight.
Lot of folks been saved because they DID remember what they'd practiced and prevailed by hitting the target under the most stressfull of conditions.
As for the hot hardball round in the chamber, NO. Years back, some, who carried .45's, adopted the practice of placing a hot UZI round (hardball) top of magazine with Speer JHP's below and in the chamber. Reasoning was that the first round from the magazine was most likely to jam with the Speer (flying ashtray) with it's big wide hollow cavity, so a harball round was substituted. At that time the Speer was the best for "stopping power" and the worst for feeding.
Don't know what tactical situation your old timer had in mind with the HB in the chamber backed up by far more efficient HP's.
