Sounds interesting Bernie, but I'd recommend a material that is more stable and won't change due to humidity and weather changes. I used refrigerator magnet on my mannlicher forend to create a pressure point, it should work for floating, too since it's a synthetic material and pretty much not going to absorb moisture. It also molds to the barrel real well and sticks to it. Hmmm, wonder if the magnetic properties would have effect on bullets just as the old cow magnets improved fuel economy!!! :-D :-D :-D
