I was curious (famous last words) if paper patched would survive the transition through a revolver cylinder to forcing cone. So apparently it does. Nine shots at 25yd, .44 magnum cases and an arbitrary load of 10.0gr Unique and patched #503 SWC (Mihec clone). No workup, zero leading, and more than half had torn or lop-sided patches that I messed up when sizing (shot them that way in the name of science). Not the smallest group, but not awful either. Probably never do it again, but it was a case of "I gots to know."
Edit: Not sure why pic is upside down.
