Re: Something extraordinary

If it is bored for paper cases there would be a problem using brass. The brass is much thinner, but the chamber dimensions are the same, so a rifle bored for brass cases uses a much larger diameter ball or bullet. A ball or bullet appropriate for a rifle bored for paper cases is too small to be held by the brass case.

To put it a different way, a rifle bored for a paper case will use a bullet or ball that is ~0.020" smaller in diameter than a rifle bored for a brass case.

The key to this is that the chamber dimensions remain the same. One accommodates a thick paper case with a smaller projectile; the other a thin brass case with a correspondingly larger projectile. The difference is in the bore dimensions.
