This changes its position and the orientation of the bolt face to the center
axis of the bore.
Tenders are invited for Design, Manufacture, Supply, Supervision Of Erection, Commissioning, Acceptance Test, Machining Trial On Standard Specimen, Alignment Of Barrel And Proving Of Alignment System At Purchasers Works, After Sales Service, Confirmation To Supply Of Spare Parts For Adequate Period Of At Least 10 Years Of Heavy Duty Conventional Alignment Lathe For Alignment Of The
Axis Of The Bore With Respect To The Machine Axis As Well As Rough And Finish Turning , Threading And Facing Operations.
If we're not loading directly down the centerline
axis of the bore, our off-axis pressure will combine with PIV to make our crosshairs hop off our point of aim.
Many have criticized this feature, claiming a short neck would not hold a bullet in proper alignment with the
axis of the bore.
With a 1911, the
axis of the bore sits lower to the hand than many of the more modern guns it competes with.
Since the Foster slug is almost as wide as it is long and considerably smaller than the bore to boot, it may or may not perfectly align itself with the
axis of the bore during firing.
Usually, though, most of the weight (stock, receiver, magazine, lockwork, triggerguard and floorplate) is below the
axis of the bore.
Good gunsmiths like Weigand carefully machine the crown square with the
axis of the bore and ensure that no little burrs or other deformities are present.
Mechanically driven parallel anvils extend simultaneously, and their consistent pressure results in more accurate readings and true alignment to the
axis of the bore.
The bases of bullets seated with run out will not be perpendicular to the
axis of the bore, causing tipping upon exit.
Add to that the straight-line stock design, which puts the shooter's shoulder in direct alignment with both the recoil
axis of the bore and the linear axis of the gas-impingement, minimizing muzzle flip and subjective recoil.
The vast majority of the rifles used here are of military origin so the issue of mechanical off set or the difference between the height of the sight and the center
axis of the bore comes into play.
