I had forgotten about this. Here is a video from the History Channel of an IMI instructor and a PIAT. If any of you guys have shot one you might find this interesting. He did not try it this way with a live bomb. I realize from this that I have been holding it wrong. No wonder I am not able to get sub MOA groups at 100 yards. I thought it was the non match grade tail fins.
