I'm having probs with 3rd shot flyer when using HSM Trophy Gold 168VLD ammo and I ordered one of those Limbsaver vib damper things for the barrel. I havent got it yet, but was wondeirng if I wasted 20.00 or if they really do work. Before I was subjected to Obamanomics and had a job and a good tv package I used to watch Eastmans Hunting Journal a lot and I see Guy Eastman used it all the time on his 30-378 Wby rifle. I was just wondering what other forum members experiences are with it. Thanks.
