twogun, they mess with arrow drop numbers a lot. It's hard to tell whether they're talking actual arrow drop or trajectory and a lot of people get confused.

Drop is firing the projectile - arrow, bolt or bullet - perfectly level with the ground and measuring how far itfalls at different distances.

With trajectory, you're launching the projectile at an upward angle, rising above the line of sight in the middle distances, dropping onto the line of sight where the sight is zeroed, then dropping below line of sight beyond that.

If that crossbow bolt is fast enough, and the sight is set for something around 35-37 yards, then I can believe those numbers. I can't say for sure because I have never shot an arrow or crossbow bolt anywhere near that fast. Don't even particularly want to, for that matter.[:-]
