I went to the range today and at 5 yards repeated my drill with live fire. My first shot was 1.82 seconds and in the "A" box. Second shot was 1.85 seconds, also in the "A" box.
I ended up shooting 100 rounds, all my reloads. A 230 gr plated FMJ over 4.4 grains of Winchester Super Target. About 50 draw and fire one shot. About 30 draw, one body shot and one head shot. About 20 with an instructor watching me at my request to see if he could spot any flaws in my technique.
First target of the day (note I used both sides, so some holes are "in" and some are "out" from the perspective of this shot. Almost all "A" box hits.
I did start stringing left as I started getting tired. I know why, gripping too hard with my right hand.
