The best advice I ever got lately was to squeeze the trigger at the break SOFTLY. If your trigger breaks at 5#, just complete the trigger pull at 5.1#.
As promised I'll try to give a good report as to the range time today. I had the range all to myself and the RSO worked with me the whole time. I started out at the 15 yd line shooting a reduced size silhouette target. I shot better than before but still needed improvement. After a bit I switched to a Guerrilla Approach Consistency drill that I like a lot. It has a series of small circles that demand accuracy and then some combinations of small and large circles. The large circles are to be engaged with a double tap.
I had to enlarge the targets for the 7 yd shooting distance at this range, but since the targets are all white it is easy to see the impacts immediately. My first string at these targets I could see I wasn't doing well. So I just slowed down to where I could feel the creep in the trigger, like at home doing dry fire, and the results started coming together. The second string I did great (for me). I decided to quit while I was ahead. I had shot around a 100 rounds in two hours and I felt really good.
So the important lessons I learned, in no particular order are: I like the white targets so that impacts are seen immediately, I need to feel the creep in the trigger before the shot goes off, I need to bring my left elbow in closer to the right arm (I think it locks my wrist), I need to rest in-between shots at times and relax my grip while doing so.
Edit to add: After sleeping on it and doing another dry fire session, I thought of a couple more small things that I did differently this time. For me I think I needed to make several small changes to get things right for me and these may change farther down the road. But, now I loosen my grip with the strong hand fingers, allowing them to move forward and giving me more room for my weak hand palm. I am now placing my trigger finger higher on the trigger, to the point that I feel the sharp edge at the top of the trigger.
The last string I was shooting about 1 1/4" groups at 7 yards and they were centered. What a change. Thanks everyone for your help and support.
