Thanks for all the advice. I went out yesterday after taking a couple of days off, and did some stump shooting. By the end of the day wondering around the woods, and just having fun shooting, I seem to have reset the "groove".
I think getting off the range really helped. Sadly, the only place I have to shoot in the evening is at the range. There are times when I have it to myself, from now on when alone, no more standing at the line and shooting at the same target over and over again.
