ohio mossy oak,
That is an outrageous amount of K.E., sir. Wow!
The K.E. formula goes like this: Speed x Speed x Total Arrow Weight / 450240 = K.E.
So, with the numbers you're showing:
350 x 350 x 445 = 54,512,500 / 450240 = 121.07 Lbs. of Kinetic Energy.
Also, here's a link to Easton Archery's K.E. page.

For a comparison, I'm shooting 270 f.p.s. with a 400gr. arrow. 52# and a 27" PSE carbon arrow and a 100gr. tip weight.
270 x 270 x 400 = 29,160,000 / 450240 = 64.7 Lbs. of K.E.
If it wasn't obvious its a crossbow..So dont be to impressed LOL...I shot RH compound till this past spring when I decided to make the switch to everything LH except pistols...I been working alot of hours and didn't have time to get a LH bow an relearn so I picked up this Stryker 380 crossbow to hunt with this year an help transition to Long guns LH..Its a powerhouse an more accurate then I thought it would be,but not near the fun that a vertical bow is to shoot...
(sorry to go off topic folks)
