Ok you gurus picking the brains again. I am by no means a speed freak as my shots are 30yds or less. My bow is rated at 315-320fps and no I don't expect it to be that fast. However with my current set up and arrows they come in at 398 after adding 20gr weights to the front end to get my FOC to 12% show only 242fps and 51ft lbs KE. Seems way off but it still works. What are the experts thoughts? All my info is in the sig.
