*** Disclaimer - I'm by no means an expert. I'm looking at your targets as if they were mine. My comments are what I would suggest to myself, I'm usually hyper critical on myself.
1st target looks like you were pushing your shots (groupings that have a prominence to the left of center). Pushing is usually indicative of improper trigger finger placement.
2nd target - Looks decent, I'd work on tightening the grouping by slowing down my shots. I'd also try to place my shots up a bit, into the thoracic cavity.
3rd target - Shots are a tad low, not sure if you placed low with your 1st shots and decided to work on groupings within the 9 ring. Work on consistent trigger finger placement (again pushing your shots). Get my shots into the 10 and X rings more consistenly.
Right now, I'm working on RDS pistol and becoming proficient. It's been humbling to have shot well with irons for so long. Only to shoot like a novice while training shooting RDS. I'll get it though.
