Artillery range, 1st Century AD

[Paullus Scipio]

Just as a matter of interest on what can be achieved, Baatz calculated ranges for stonethrowers allowing for 'wind resistance' of over 400m ( see for example the chart reproduced in Duncan Campbell's "Greek and Roman artillery") based on an initial launch velocity of 70 m/227 ft per second. I know many of us follow fellow RATter Joel's threads on his 'inswinger' catapult as it steadily climbs in power, toward velocities almost double this (425 ft/130 m per second) - for a bolt-shooter.

This has been achieved with just four years of 'tuning'.....what might a late Roman catapult be capable of after 6-700 years of development? hock: hock:
The videos of this machine in action are truly impressive.....
