don't know where I heard this from, but I tried it once on a mover at a fair distance (I think 15-20y). I didn't notice it until I saw the video, but I basically locked up on sight, and my body moved on my upper hips, it seems to work, I shot at it 4 times and hit it with 2 A's, and I think 2 C's. It seems to work for me and instead of waiting for the popper to stop at the point it returns direction. I think I shot at it extra times because I am just used to doing that....because I missed to fast... 7 rd stage turned into a 9rd stage.
be kind, i am new, but here is the link;
