.Ok, so you can feel the node on a bull rimfire barrel, and use a tuner to move that point to the crown. But what about other barrel configurations? Does a fluted barrel resonate differently? What about a "Running Boar" muzzle weighted barrel? How does tapering effect this? Seems each would require a dramatically different weight tuner, or am I missing something?

The NODE of other barrel configurations

Barrels are like snowflakes no 2 alike, similar but not the same. A short bull barrel will require more weight to cause an effect than a longer one and either the those would require more than a skinny sporter ( leverage 101) Running Boar - weights were not for tuning, were there to try and slow your offhand wobble and to give a better follow through swing. Tapering - yes. Last sentence- part a Yes, depending on your definition of dramatic, part b No (Shields at 100%)
Metal bars vibrate at different amplitudes and frequencies depending on their dimensions, weight, and modulus of elasticity. The "node" I think you are referring to is located about 2/3 the length out from the receiver. You may be able to "feel" this in a vibrating barrel but not likely unless you have struck the barrel with a lot of force. Tapering a barrel will move the node out toward the muzzle slightly. Fluting a barrel simply makes the barrel stiffer relative to the weight and thus it vibrates the same as a solid barrel but with different amplitude and frequency.
"Resonate" is probably not a correct term to apply to barrel vibration. A steel bar will only resonate when the force causing the vibration is applied in such a way as to reinforce or increase the amplitude. It's necessary that the force be replied several times, or for some period of time, to cause resonance.
It has been determined that moving the node toward the crown is probably not the best way to increase accuracy. I think most now accept Varmint Al's analysis that indicate you want to move the bullet exit from the barrel so it occurs while the muzzle is moving away from the axis. Adding weight to the barrel, or moving this weight will accomplish this.
