If you want to see and read about barrel nodes go to Varmint Al's web site it's all there with animation actually a barrel will move up and down more than in a circular pattern. You want your bullet exist on the up swing of its movement when the bullet is traveling down the barrel and ready to exit the muzzle.
There is usually two nodes that center fire benchrest shooters talk about the low end node and the highest velocity node. long range shooters want to hit the high velocity load node for better performance at long range. Since muzzleloaders are bore rides they are not as touchy as a center fire for finding the sweet spot for best accuracy.
If you ever have used a barrel tuner that is it's sole purpose to get the best node nearest to the high point of the upward swing of the barrel when its fired. Everything effects the barrel harmonics from firing spring tension to trigger timing scope mounting head space and how much you bump or size back your cases everything causes a vibration that all is transmitted down the barrel. I have put heavy bench guns in my mill vise and clamped them down and placed a dial indicator out on the end of a 30" heavy 1.450 that is glued into a 8" long bedding block and the stock is made out of aluminum and when you cock the bolt and dry fire the gun that has a 2 oz trigger just the firing pin fail will cause the indicator on the end of the muzzle to bounce several thousands and then come back to zero. If it didn't come back to zero then there is a bedding problem.
