Bounce

From the V8 Rulebook: Projectiles:

This category includes thrown weapons (axes, rocks, daggers), javelins, Magic Balls, and arrows Unless otherwise noted projectiles may not be used to parry, block, or melee, are indestructible, and affect all targets struck while in motion.

This means that a bounced projectile does inflict a wound.

Note:
This does not apply to Magic Balls due to rule 5 under magic balls

5. Magic Balls only affect the first thing they hit.
