Some guru will come along in a bit and make a guess at your possible drawlength and arrow weight combinations to get that speed but I'm not that good.<img src=icon_smile_wink.gif border=0 align=middle> This would probably be a very simple question for someone else if we had some other info like:

What do you have on the string?
What cam and limb combination does your Ultratec have?
What is your draw lenth?
What does your arrow weigh?

You won't have a problem hunting with that speed at known distances, IMO.
