I imagine velocity and BC help mitigate the effects that the narrator uncovered since they were using air rifles?
'Morning. To start with, none of this was "uncovered". These effects are well known and have been observed for decades. What this did so well was to show how well the predicted result (exterior ballistics) matched up with the actual result (real shooting). And while the numbers will change based on the exterior ballistics (B.C. and velocity being the primary drivers), the
pattern will always remain the same regardless of the cartridge used.
And while some of this has little to do with the shooter/hunter doing load work, it's pretty easy to see the wrong turns and dead ends shooters get sucked into taking...lacking some sort of even the most basic wind indicators.
So does a bull barrel significantly tighten the dwell and make the node "larger"?
Barrel mass (weight) and stiffness shorten the amplitude (high/low peaks). This has the effect of extending the dwell time. Interestingly, barrel contour as relates to stiffness is not always what it appears to be.
Good shootin' -Al
