Well, IMHO, the most important thing I learned from #6 is trigger control:
Someone, somewhere did a test. They used a computer to track the point of aim while someone aimed their weapon at a target offhand. The resulting "picture" closely resmbled the kind of picture you would get out of a spirograph (hopefully you all know what spirograph is)(if not chime in and I'll try to explain) Anyhoo, the results showed that while yes there were little loops drawn away from the center all around the perimeter where the POA was off target, something on the order of 95% of the time the POA was dead center or in other words the center was blackened in with little "flower petal" loops around it. Picture a daisy I guess. So what was learned from this is that your body has the built in ability to hold on target, all by itself, 95% of the time. What does that tell us? We DO NOT need to concentrate on holding on target. It will be done automatically. So what does THAT tell us? We need to FORGET about how the sights are wandering all over the target and concentrate 100% on a NICE EVEN TRIGGER SQUEEZE so that when the hammer releases it is a surprise. What THIS does is take the blink or flinch out of the picture. He told me everybody flinches or blinks. Even if your EYES don't blink your MIND does. The object is to get that flinch to come just the split second AFTER the shot is released. That's why a surprise trigger break is so important. If you KNOW when the gun will fire you will incorporate your flinch into the shot. That's called "anticipation" or "anticipating the recoil" if you are surprised by the gun firing, the flinch will come too late to have any effect on the shot. If you try to pull the trigger ONLY when the sights are perfectly centered chances are you'll jerk the trigger almost every time. Once you have learned to do this SLOWLY you will maintain your nice trigger squeeze when you start to speed things up. Another great shooter (IDPA style) tells me, "Concentrate on accuracy and the speed will come. THE SPEED WILL COME!!" ( Yea, I was gettin' yelled at at the time.
) he was ruight though. These days I'm a bit faster and the bullets usually go where I want them. I don't know HOW but they do.
And there IMHO is the biggest secret. LET the sights do what they will, YOUR JOB is to ignore that and instead release that hammer as a surprise WITHOUT DISTURBING THE GUN!!
This works even for rifles at long distanceas well btw. I've tried it.
Well, I think that's the gist of it. Naturally theres tons more but this is the biggest part IMHO.
