Any well run reenactment allows NOTHING down the barrel but the powder - no paper, no wads - NUTHIN! In fact, ramrods are left in camp to prevent such a thing - and the possibility of sending a ramrod down the field. Even a felt wad over a powder charge in a revolver can cause damage if some "yokel" decides to do it and aim his weapon at a person and let it go - the obvious is eye damage not to mention the possibility of the wad entering soft tissue - lead, paper or felt - it's a projectile.
If he doesn't have anything to hunt with . . . I'd question how "good" of a hunter he is. I'd be more worried about tying him up in the tree stand to make sure he doesn't fall out.
