I have 45/70 inserts for 12 gauge. They are about a foot or so long. The shots crossed horribly. I couldn't get 500 grain bullets at very low velocity to come close to convergence. If bullets out of a double rifle cross they are too light or too fast. If the shoot apart they are too heavy or too slow. They are held in with O rings. I though of shaving a side of the O ring and twisting the insert until I was hitting point of aim. Never got around to it.
