You might try looking at it like this:

When the bullet is fired, the barrel starts vibrating back and forth, much like a string on a guitar. The muzzle of the barrel is whipping back and forth, but as it goes one way, it has to come to a complete stop before it turns back and goes the other way. Theoretically, then, the barrel actually stops its movement for a fraction of a second before it heads in the other direction. Heres where a barrel tuner comes into play. Since the tuner alters the vibration pattern, the shooter is attempting to modify that motion to get it to be at that stopping point, just as the bullet leaves the muzzle of the barrel.

IF all the ammunition is exactly alike in speed, and IF the powder charge is creating exactly the same vibration every time, then, each bullet will leave the muzzle under the same conditions (the theoretically motionless barrel) and its theoretical flight path will be identical to all the others.

In the real world, there will always be a minor difference between the actual speed of the bullets, and each ignition will create a slightly different vibration pattern due to some inconsistancy or other... but to a large extent, the conditions will be similar. The more similar, the tighter the group.
