[QUOTE="tacomHQ, post: 2605226, member: 67159"] Perhaps I might be that guy..LOL. We are not only looking to reduce overall "whip", harmonics, etc... to reduce the time line of the event. I think we are getting somewhere as we have multiple shooters note that their barrels are flat out the most accurate barrels they have ever had- across a broad spectrum of loads. Velocity- a constantly evolving pressure event will create a better seal .. arguments coming ... especially in a hostile environment. The other velocity comes from changing directions. When a barrel goes into a sinusoidal whip, the bullet has to change directions. Changing a direction is a loss of speed no matter how small the value is. If I change direction 4-20x within the barrel velocity has to be lost. Even if its only 5fps... or 150fps... We have a shooter who shot a test AB .338 bullet at 300gr at 3450fps with no bolt set back. Now to make the barrel survive that for a few thousand rounds.. [/QUOTE]
