One technique I know of is as follows:

Bow is off-the-shelf practical and useable. Arrow is
fake.

Arrow is constructed of hollow plastic tube -- like a
very long drinking straw. Feathers and soft tip (also
hollow) are added.   This arrow is very lightweight
and virtually harmless. Tip can be made sticky with
spray adhesive.

One end of thin guide wire (monofilament) is
attached to center of bow's drawstring. Hollow arrow
is fed onto this wire. The bow is now loaded.

The opposite end of drawstring is attached to it's
predetermined target -- scenery, prop, even the
actor's (victim's) costume.

As the shooter picks up the loaded bow with arrow,
he positions himself to "aim" the arrow, when
actually he is merely drawing the slack out of the
monofilament.

With the wire now taut, he can shoot the arrow with
utmost accuracy as it will travel along the wire until
its soft tip (wetted with spray adhesive) "sticks" the
arrow into it's target.

If the arrow is fired into an actor, the actor can catch
the arrow as it strikes, holding it in place as he dies
or flails about dramatically. The actor holding the
bow only needs to take a few steps forward to allow
the "dying" actor all the slack he'll need.

Happy hunting!

Will defiantely give this some thought. Some once mentioned magnets but only hypothetical. Never actually tried.

Thank you for the detailed suggestion.

 

Anyone else, please feel free.
