Brian- Being an archery dealer at one time and into music I can tell you that limb savers work on archery products by way of the different material causing destructive vibration to silence the limbs. I don't know exactly but I would bet that it would make the barrels vibration less predictable and cause more variation that it would cure.
However there are a lot of guys on here that would not mind your input should you try it. I am betting it is like a stock contacting the barrel but could be wrong. If you try it please let us know how it comes out.
