Throwing a Pilum in Armour - How far can a pro throw?

The Romans used a pilum or a version of it for hundreds of years and it was used to harass the enemy from a distance and help break up shield walls and formations just before fighting lines clashed and it was very effective. But how far could a legionary throw one? I cannot throw well, but Michael Allison throws javelin for Team GB; he can throw! So I have recruited him again to throw for me wearing no armour (like skirmishers), just a mail shirt and wearing the mail and holding a shield. Running and standing. The first Pilum film with Michael is here For commissions and custom work For budget medieval weaponry of fantastic accuracy and value For merch For those who enjoyed Arrows vs Armour Many thanks to Michael Allison Many thanks to Adam Rudling for lending the pilum and shield
