[QUOTE="Jay Kyle, post: 1228576, member: 347"] True - a top-down approach would be better - for example military funded schools - but those would likely have a focused curriculum that may not have time for smaller extra-curricular projects such as this.... it was a thought. However! the articles you brought are insightful. The first - Using Barrel vibrations to tune a barrel - does support Brownings BOSS technology (et.al) The learnings I take away from both are: [LIST] [*] A barrel with a BOSS like tune-able weight on the end provides a mechanism to tune the 'whip' to coincide bullet exit and a common point in the whip cycle [*] An experiment of relieving the gas pressure - before the bullet exits the barrel, to relieve muzzle gas wash, in conjunction with a barrel tuner, would be interesting. [*] Barrels with decreased diameter toward the muzzle can contribute to secondary pressure rise, in the presence of other influential factors such as too-slow of a powder. [*] Lastly, I thought it would be interesting to understand the complete motion of the all of barrel during the vibration event, but in reality it's the influence on accuracy that seems to be the most sought after information.[/LIST] ..sometimes I wish I was back in school.
