Ok I know this is some type of mental error and probably just sloppy fundamentals but over the last year I have started shooting PRS style matches and one of my big weaknesses was speed, I was slow on my shots. I have been working on that and I have improved greatly but I also have noticed my 100yd groups size is suffering. I was shooting prone .3 best to .5 average groups, but now I still get .3 on occasion but my average is .8. My down range accuracy has improved as well as my speed to break the shot and to transition so I pretty sure it is the nut behind the rifle. Any drills you guys would suggest to work on this or just don't worry about it and keep shooting.
