[QUOTE="Veteran, post: 2228289, member: 118038"] Here's another site I found today that seems very data heavy, scientific and conclusive concerning barrel tuners and harmonics. They cite Varmintal's a few times too. But their data and experiment is really interesting. [URL='http://www.targetshooter.co.uk/?p=660']Part 1 http://www.targetshooter.co.uk/?p=660[/URL] Part 2 [URL]http://www.targetshooter.co.uk/?p=536[/URL] Part 1 is more interesting and more informative. Part 2 is all of the statistics, and you gotta have a cup of coffee to get through all of that unless you just love statistics, with confidence intervals, T tests and such. But excellent analysis and presentation. One other thing I did today was investigate the Ezell PDT tuner that was mentioned above. I had never heard of it, and it is very interesting to me because it is using an enhancement over just weight and axial variation of the weight. It uses Particle Dampening Technology from a Thesis written by a Grad Student at Texas A&M in aerospace technology. I suppose those big jet engines and turbines can cause a lot of harmonics throughout an aircraft frame and enough vibration will cause them to rip themselves to shreds. So, the PDT Tuner has tubes filled with Tungsten and that is what is varied axially along the barrel to Damp out harmonic vibrations. That is a pretty interesting new thing I hadn't heard of before either. [/QUOTE]
