Next and possibly final attempt... I'm getting frustrated.
All shots at 21 feet. First I make sure the pistol is zeroed, 8 shots from a semi-steady rest (top target):
For all groups I try focusing on front-back pressure from the grip, no lateral pressure, good trigger position, etc.
First group, pistol canted 10-15 degrees:
Then I try holding the pistol vertical, and facing the target more directly:
Then I try canting it 45 degrees (note the very low hit on paper and one off the paper:banghead:
I gather myself for one final attempt, focus on fundamentals, etc.
I wonder if maybe it's the full-power .45 ACP causing me to suck, so I switch to the P226 9mm.
Then I decide maybe I've chosen the wrong hobby.
I shoot some .38 to work up some loads, then I try one more magazine of my .45 LRN loads at the steel plates, and hit 6 out of 8.
I think the fundamental issue is that my weak hand/arm actually is weak. the gun is moving all over the place. I can't get my sights to stay on the target long enough to get a "surprise" break. So I must be jumping on the trigger to try to make the shot.
