Some links

On the forum "Accuratereloading.com", the thread "Effects of Tiny Variations" on velocity yielded some good thoughts. It would be worth reading.

It also has links to these articles which are worth reading, too.

and I wish I could find more details about this demonstration performed regularly in a master loading class conducted by a bullet manufacturer.

Shoot at one minute intervals and compare the two groups.
or compare the strings of velocities for uniformity.
