If a 630 grain arrow that weighs 110 grains heavier than mine, but still get up to 245 fps, what is so difficult in believing a 110 grain lighter arrow will do 285? And, you are forgetting that the " speed x speed" portion of the equation is an important factor in KE. I don' t care if your arrow is 1000 grains, if it' s traveling slow, it' s not going to have the KE. If it' s traveling fast, use it for anti-tank.

And it wasn' t just one chronograph I shot thru. If you read the post, it was several, different ones, owned by different people, at different archery events. But, this is getting ridiculous and taking away from the original question of this thread. Have a nice day.
