Barrel nodes / barrel whip / vibrations ??

[hemiford]

Not sure how to put this question into words.....

For any given barrel contour and length, will shooting heavier bullets through it cause higher amplitude vibrations
than shooting lighter bullets faster through it ? This would be for the same cartridge but different bullet weights.

Will higher pressures behind a given bullet cause higher amplitudes of barrel vibration ? (Load differences)

Great question. Following

It's not just the bullet weight/barrel contour but also the bullet acceleration/velocity that will affect it
Look for article by Chris Long and

Just a little too advanced for me, know enough to use it for my purpose
