So, I do find this very interesting, and with that in mind it reminds me of a Rifle that my Brother in Law had built, in Pittsburgh Pa. a few years back. During hunting season, we had are deer, hanging, and it was a rainy day in the middle of the week, I took a ride with my Brother in Law, to pick up his new custom made Rifle from Accuflite in Pittsburgh, a couple hours from our Hunt camp. The 300 Win Mag my Brother in Law had built had a reverse tapered Barrel, to solve this very same so called problem of Barrel Vibration, and Harmonic Balancing! I liked it so much that I had to order one myself, and since have shot several game animals with it, with tremendous accuracy! Jim at Accuflite is the Owner, who was a nuclear physicist, and is very knowledgeable!
