crossbow continued

Well, in using the intended Kleenex ammo, the crossbow simply doesn't get to be accurate.  The closest thing to getting accuracy achievable is in VERY carefully choosing the spot on the rubber bands which is centered in front of the firing mechanism (say "clothespin") and pulling it back at exactly that point.  Otherwise the bands themselves will send the shot off in an unintended direction.  Then adding in the lightness of the Kleenex ammo, any current in the air send it some other way.  As for OTHER ammo... working on a sort of rail system to help guide the bolt straight out to the end of the bow.  And searching for better glue to hold on the "flights" as the guidance fins are called.  Barking dogs beware! >:)}
