Not really a crossbow, but what I hope is interesting information on the effectiveness of a somewhat similar weapon, the Roman scorpio - a torsion powered "bolt thrower": (jump to minute 11:00, in German)
The testing took place at the Fraunhofer Institute for High-Speed Dynamics (
With the weapon in the video above we ( managed a maximum of 12 bolts fired in 60 secs with a 3 man crew after some hours of scorpio drill over 2 days and a few adjustments on the weapon.
