a bow shooting 272fps to go 20 yards .22 seconds
a rifle shootin 3000fps to go 300 yards .3 seconds

I think that is right. I haven't had any math classes for a while! LOL

But then again - a rifle going 300 yards is going to loose lots of energy/velocity, which isn't taken into consideration.
A bow shooting 20 yards isn't going to lose near as much energy/velocity.

I got nothing - its too late to be figuring numbers!

Then again - I don't know if a hornet will even go 300 yards and hit the desired target in the desired spot [:'(]
