I know how most of you guys are gonna feel about it, and I know especially with heavy contour barrels, results may be negligible, but have any of you guys ever seen positive results from the Limbsaver Barrel De-resonators? Just ordered one. I don't think it would hurt anything. I've read that moving weights up and down barrels can improve accuracy if you find the "sweet spot." I also don't care that it looks like a doughnut shroom.
