I have a hoyt havoctec. I was wondering what my speed would be? I am shotting 28 inch draw, 70 pounds, and a 350 grain arrow. also this bow has the versa cam. what would it be if i dropped the draw length another inch?
Assuming you have no string accessories installed I would guess around 280 fps. String accessories can lower speed further by an additional 3-8 fps per item with rubber string silencers and a rubber tubing style peep sight being the worst "offenders".
Reducing your draw length another inch will approximately reduce your speed by another 10 fps.
