That depends. Every aspect changes the FPS and ft/lbs of energy. String usage also chages things.

65# Longbow shown below. 50# recurve with 3/16 off center shows 37.7 with exact same arrow setup v. the 46.5 ft/lbs from the LB.

I must have Stu's old calculator, the one with the arrow and bow inputs only. Is there a thread with this calculator on it.

Compared to some of you I get low KE  :p
Only 33,7..
In Denmark, the closest place for me to hunt
you must have minimum 40 KE regardless if you're
hunting small or big game..

Here's my inputs  :)
