[QUOTE="J E Custom, post: 1807098, member: 2736"] Think about it this way, If the chamber is perfectly aligned with the bore, and the case perfectly fits the chamber And the loaded ammo Is perfectly concentric, even though the bullet is not touching anything, It will be aligned with the bore and when fired will have a better chance of concentric engraving in the rifling. This is purely a mechanical alignment. Loading ammo that perfectly fits the chamber and perfectly aligns the bullet with the bore is the goal. Placing Prussian blue on a bullet will not tell you it is touching the neck wall but that it is not feeding correctly, The marks shone on one picture are from contacting the chamber edge at the back as it is fed in by the bolt, but with mag tuning it can be eliminated and prevent damage to the bullet. Ideally, The bullet never touches anything while being chambered until the last as it is going into battery when the bolt is closed. Factory chambers and rifles are seldom perfectly aligned with each other so full length sizing is probably the best route for you. Anything you can do to load better ammo will help.
