Audible Node Harmonics

[Front Royalty]

I have read here and a few other places that some shooters can actually hear when their load is on the node, like somebody hit the muzzle with a ball peen hammer. An audible "TWAAAAAANG". I heard this for the first time yesterday at the range. Its unmistakable. Pretty neat, actually. It happened 3 times during OCW testing, each time at 41.5 gr IMR 4064 behind a 175 TMK in .308. It appeared to be ****ed close to the center of the node but Im going out on a limb and keeping the charge weight for research purposes and playing with seating depths next.

Anyone else hear it?

I can hear and feel it,, to me it's like a (BOING) sound.

[LongRange]

my muzzle breaks must be to loud or im just not listening lol.

exactly!

that's a fact
Theres harmonic rings that appear on my fluted savage barrels. you can see them more on my HS Model 10 than on my Model 10 K. Not only can I hear/feel the resonance but I can see it on my barrel
Were using almost the same components
Im running 41.5 4064 and SMK,s. out of my 24" 1-10. 2700fps

Oh my...

Well I certainly don't expect to convince people it exists, or that its a sure fire indicator, all I'm saying is that I can hear it.

[cowtownup]

I'm not doubting you man, I'm just doing my best to try and control a few of the many variables this hobby presents and now you go and add another one... Shame on you... HAHAHA...

[Robinhood]

Would you call your barrel a hummer?

how fast?

[Hotolds442]

I certainly believe it exists, however I'm usually too focused on the shot placement and follow up to notice.
My barrels may be humming, but apparently not the right tune.

My hearing is not THAT good...but I can usually smell a good load.;)

Chronograph was out of commission, not entirely sure.

you beat me too it!!!! Hahaha! Seriously though No I can't hear it or smell it. I feel a bit handicapped I have to see it on the paper. I haven't been doing this very long, but I'm thinking its probably a little like the old timer that can tune a motor by hearing/ feeling alone.

You've been hanging around shooters long enough to be good at smelling lots of things. lol

[doctnj]

Just been going back in my mind to see if I remember anything like that and I think the answer is no. The closest would have been on a Henry repeater. When I shoot it, I hear "indians". :}

[Zen Archery]

Well I wear ear plugs while shooting so... Bwhahahaha...

My hearing isn't so good anymore so when doing load development I place a trained lady bug on the barrel about 6 inches from the end. Typically the bug just sits there, but when I fire a round with exactly the right powder charge so that my rifle/barrel/powder combination hits the perfect node, the lady bug extends her wing covers as if getting ready to fly. She's trained not to actually takeoff, but the indication is clear. Each time I hit an accuracy node, she extends those cute little wing covers. Apparently lady bugs are really good at detecting certain kinds of vibrations. Anyone can try this method, but I should warn you, the training routine is long and difficult.
