Cloud just keep putting heavier arrows through it and you will get more and more KE.

My hunting bow set at about 58 lbs 29 inch draw will shot a 300 grain arrow 292 feet per second. which is 57 ft lbs.

I settled in with a heavier arrow 411 grains going 262 which gets the KE up to 63 ft lbs. I find the bow is quieter with the heavier arrow, I can live with the trajectory and I got the KE I was looking for with a lighter draw weight. results in a well tuned rig that is very effevtive on whitetail deer.

Lot of trades offs to consider. Speed versus KE versus draw weight ect.
