Re: Limbsaver Barrel De-resonator...myth?
I'm no scientist, but it seemed to work on my cousins Savage. He has a 26" barrel and he found a sweet spot that tightened up his groups. It may be a mental thing, but I know as he slid it up and down the barrel to find the sweet spot, his group size definitely changed. This however is on a rifle that is shooting .75" groups consistently with hand loads. I would say it helped to shrink them to about .5".
