I think this is where Rybohunter missed the boat. A bow will not produce the same KE for any arrow set up.

I came up with 56 ft lbs of KE on Jackson's, but whose counting! Having said that, it is plenty for white tailed deer. If I was going after Elk, moose, bear, etc, I would want a little more KE. Just make sure you are using a good fixed blade broadhead. I would steer away from mechanicals. How long is your draw length? Do you use rubber tubing on your peep? What is your string loaded down with? Are your limbs bottomed out? These are things that can be addressed to maybe give you a little more umphhh!!! If it were me, I would lighten that arrow up somewhat as well. Good Luck!
