Since finding your accuracy node is so critical when it comes to long range shooting why don't more of you spend the $11 to experiment with a Sims barrel de-resonator also called the Sharpshooter X-Ring or have you??? If you have then what were your results? I started a topic a while back on this but only got 1 response and that person said he uses them on 4 out of 5 of his rifles and swore they made a noticeable difference. I bought one and plan on doing my own tests with it but in the meantime I would like to hear from those of you who have tried them already and if you haven't WHY NOT??? IT'S ONLY $11!
