Gibbs Posted August 24, 2014 Report Share Posted August 24, 2014 I love to hear opinions and thoughts. I have read and heard about ways to dampen or change the barrel harmonics of rifles. What I understand is that there is a sound wave that travels at the speed of sound through metal when the cartridge is fired. VERY fast, much much faster than through air. In fact it is said that this shock wave hits the end of the barrel, heads back to the breech, then back again to the end of the barrel several times before the bullet has had a chance to exit the muzzle end. I have read that it is important that the shock wave or "harmonics" have not coincided with the exit of the bullet at the muzzle end. I've even Seen a system on one rifle, in video, BOSS (Browning's paten on Ballistic Optimizing Shooting System ) *google search BOSS barrel tuner, and you will see this. You tube video even has a clip on it. What's the opinion of the .308 crowd? There is only a short distance between the gas block and the end of the barrel and was not sure that harmonic dampening can have a benefit in that short distance.
