I was working at a rifle range a while back and had a guy come in with a BAR with the BOSS gizmo on it. He was trying different factory loads to figure out which grouped best, and how to work the BOSS to tighten his groups. He'd found the best load of what he had with him, and then started playing with the BOSS. He got that thing down to consistent 3/4" groups off the sandbags by working with the BOSS system. The only thing I've never liked about those guns was the weight. The ones I saw out there shot better than the Remington Jammamatics, and ran smoother too.
