Bore axis shifts can present a challenge to the long range shooter. One of the primary mechanisms for bore axis shifts are harmonic and vibratory inconsistencies due to problems with rifle system rigidity. Inconsistent whip action can occur when the movement of the projectile experiences frictional changes on its way down the bore due to various affects. Rifle rigidity dynamics also play an important role in ensuring the harmonic consistency of a vibrating rifle. In this video Rex addresses the issues related to barrel / stock contact points, stock warp, lockup of bolt lugs, chamber dimensions and headspace.
