tacom structured barrel

kthomas said:

If you think of the barrel as one that moves up and down in a sinusoidal wave pattern, projectiles traveling at different velocities will exit the barrel when it's at different positions in that sinusoidal wave. Some velocities will result in the projectile exiting when the barrel is pointing up, others while the barrel is pointing down, which results in a hypothetical vertical dispersion.

If you can "deaden" that barrel by removing, or at least mitigating those sinusoidal wave patterns, aka "harmonics", you reduce the vertical dispersion in projectiles traveling at different velocities.

At distance, you're still going to get vertical dispersion due to differing velocities - that's physics that isn't overcome by a structured barrel.

Look at all that barrel whip………

I understand the ballistics of the bullets hitting the same point of aim. That's not the engineering of a structured barrel. And if it was something to do with harmonics I would need to see how that works like with the above slow motion camera. Cause I would think a straight 1.2" tube would have minimal harmonic deviation. But I'm not going into that abyss.

The basis is the harmonics and a few small other things. It is well known that a straight barrel tend to whip less. What they have done to what in reality is a straight profile barrel is to block the path of the barrel’s harmonics. They flute and drill based on computer simulations of the barrel’s harmonics. They are also changing the cooling thermodynamics reaction of the barrel. As I have said a few times I understand the Engineering of the idea. What I am unconvinced about ( due to the incomplete test protocols) is to what extent they are actually making meaningful change.
If is interesting that the new Noveske DDF series of barrels is claiming the same benefits. They have used a different easier path , no holes but deep rounded flutes, to gain the same results. This in principle should gain some of the desired outcomes with the ability to built at rate.
I am still interested, not enough to buy one, but interested nonetheless. I am waiting for more concrete studies and victory plaque evidence. But as always I love true innovation.
