Antler Eater,
I dug this up from my review of the Pat DC last year.....
I had the opportunity to fire the bow through the chronograph a few times with my typical 430 grain Beman ICS 340 hunting arrow just to see how fast this puppy really was when using my typical setup of a 70 lb draw weight and with the 30 inch draw length module installed. Over a three day time period I shot the bow approximately 60 times through the chronograph. Average speed figures for the setup listed were between 294-296 fps.
That was with a full setup on the string if I remember correctly....peep sight, brass nockset and rubber eliminator button.
Throw another 100 grains on there and you are talking about speeds in the 274-276 fps range.
