RE: grouping at 20 yards
It's mental. I have only been shooting instinctively for about two months. Somedays, I group real good at 25 yards, and other days I don't. I found an old can huggie laying around and tied it to a rope and hung it over my target over the bullseye. My grouping tightened up a lot. Try this with something about two or three inches in diameter, tennis ball maybe, and see if that helps. Oh, and, I know what you are talking about LBR with the three D target. BTW, I narrowly missed a big rabbit yesterday with my unknown brand recurve. The arrow hit the ground about two feet in front of him. I thought I was gonna get him on the first bounce. This is very addictive.
