Resonance of a mechanical object does not change with the style of input. It is still what it is. At most the amplitude would alter due to the direction of the impact. From the side to find the node and along the barrel when shooting. But the trick is that even from shooting things are out of balance by enough that some of that goes into moving the barrel sideways. And then the nodes come into the picture.

Interesting. Please report your findings.
I think it is important to keep in mind that a barrel can be flexed slightly by pressing down on it. Most of the single shot rifles have two piece stocks which means that wherever on the barrel you rest it, you have to be very conscious of how much pressure you are putting on the barrel. I think the big reason for resting the gun near the muzzle is that it probably permits the least amount of wiggle

I'll be sure to do that. Today though it's the unloading of the new milling machine off the back of the truck.
Another example just came to mind as I was reading your post. Guitarists will know this one. All the strings will do over tones at the same fret points that correspond to the exact nodal points of 1/2 the length of the strings, 1/3 the length from either end, or 1/4 length points from either end. But due to the strings being plucked at the bridge end if the higher overtone nodes are touched near the bridge or near the nut the tone changes.
Of course guitar strings don't have a receiver and shoulder stock sticking off one end. So that will alter the harmonics in the barrel a lot. But the point is that one should be able to find a couple or three nodal points along the length of the barrel.
With any luck I'll get to try this tonight. Or I'll be up to my elbows degreasing the new mill....
