Once the round is chambered I don't see how it can move through the barrel not centered. How would a small error in the centering of the bullet in the case change this? |

Now you measure the bullet's concentricity, but what about the case? Think about a lathe. |

I would measure several points on the full case to proof the centering of the case. |

I keep feeling like I'm taking one step forward then two steps back. And, your forum suggestions helped a bunch, too. Thanks! |
