50/70 bullets

I . You absolutely cannot find a reference to any of this behavior from the buffalo hunters to the Creedmoor shooters. Why is that ? BOBW

Actually most of the Creedmoor shooters and a bunch of the buffalo hunters didn't reload any ammunition, they shot all factory stuff.
In Perry's book he says that if you choose to reload your ammunition throw the cases away after the second firing, as they will split, separate and other wise create poor scores.
Fruend came up with his improved sharps action that cammed the cases in, due to having got tired of trying to shove reloaded cases in the chamber and having them go off in his face...The sizing tools of the day wouldn't reliably size the cases down enough.
