If you are talking about KE or impact, the only calculations I have are theoretical. KE should be between 74 and 76. I want to go to a friend of mine that has a shop and a bunch of cool toys and find out because, with my heavier arrows moving at 240 fps, my estimated KE is still within about 2 lbs. Now with the heavy arrows, my flat flight is about 20 yds. and 40 is my outside limit on a shot with them. But there is a 100gr. difference in weight between the two. 2413=473gr, 2219=576gr. I also have a 65% let off, not 85% so there is more stored energy applied to the release of the arrow.
