Velocity Node Estimator Tool Below
This tool is incredibly powerful. The science of the fundamental harmonic node in our barrels is all about velocity to a barrel length. One number is important and that is the bullet exits .410 milliseconds after ignition. This has some variable with powder and barrel manufacturing.
What Efficiency to Use
We have found most of our BSF or custom-configured barrels at at about 95% with the faster burn rate powders - which are preferable for shorter barrels anyway.
Reality of Shorter Barrel Lengths
The reality is that the velocities needed to reach the fundamental node are not possible in some cartridges at all - and likely not possible in longer barrels. You will find yourself concentrating on 12.5" to 18" barrels as the ideal precision predator combination.
Skeptics
There will be many skeptics. Old school - old way. This always worked, And so on. It worked by chance and luck that they stumbled on a combination of a barrel, ammo, and load that hit a secondary or tertiary node.
Bullet Selection
These velocity requirements are absolute. So, you simply choose your cartridge and projectile that make it happen. Sometimes the lighter bullet is too fast, so go heavier and slower. Watch your external ballistics and you'll find the combination that works for you.
Velocity
Not too much, not too little. Just the right amount.
Efficiency Estimator
Since the key measurement is the .410 ms it takes the projectile to exit the barrel, we have to estimate the average velocity from zero until the time it exits the barrel and we measure muzzle velocity. .410 ms depends on how rapidly the projectile accelerated from zero. This would take costly and complex equipment. So, we estimate the average velocity (AV) in the barrel as a percentage of muzzle velocity (MV) A good starting place for load development is 93%. If you are getting vertical dispersion, you need to adjust the load up or down until that vertical dispersion is minimized. You have found the node. With that MV you can use our estimator tool to estimate your system efficiency which varies by many complex variable such as powder burn rate, barrel tolerances, bullet construction, etc.
