That thread completely misses the point from the second post onwards

Accuracy has everything to do with a consistent barrel harmonic

Everything you do with ammo alterations/ bedding/ tuners etc is to alter barrel harmonics so that the barrel crown releases the projectile in the same harmonic “place” as the previous shots

A muzzle moves considerably in relation to the point of aim with each shot

The more consistent you can get the harmonic “ wave “ as it travels the barrel the more “ accurate” the rifle

All barrels flex with harmonic waves -watch a 50 fired in slow motion

To repeat - all ammo adjustments alter barrel harmonics, there’s a huge complicated synergy between internal ballistics and barrel vibration/harmonics

Some ask the question……why/how does ammo adjustment alter accuracy, it’s because it alters a barrel harmonic

This article barely scratches the surface
