If you read the link I added it said that 250 yards or 750 feet is the maximum range not the effective range of the most powerful bow that was ever made in mass. From what I have seen no modern bow has matched it but there might be a specially designed bow that was built just to beat it.
Now the Ballista had a theoretical range of 500 yards of fire. In real use the Ballista never got that kind of range because of problems with the materials used in its constitution. The Ballista is a artillery version of a crossbow.
