Maybe this rule is clear to everyone already, but it seems I have seen it misapplied so I thought I would post this clarification I saw on the SASS Wire:
The SASS Handbook says that "A Gunfighter may not holster revolvers with the intent to engage another revolver sequence." (Handbook, p14)
This should not be interpreted to mean that if a gunfighter UNINTENTIONALLY reholsters with a live round in the gun, s/he cannot redraw the gun and shoot the forgotten round. It only applies to intentionally reholstering with live rounds (e.g., on a split pistol stage).
