I haven't put mine through the chrono at all but I will next week just to see how fast the XT is once my hunting shafts show up and I have a chance to build a few of them. My hunting arrow should come through at just about 405 grains, and I will be drawing 70lbs, and 30 inches. I don't know how fast it will be coming through the chrono at but I am willing to bet it will be 290 or better. Not too shabby considering it will be 50 grains over IBO ratings, and certainly fast enough for anything in the eastern whitetail woods. As a matter of fact, this will be faster than how I have my primary 3D bow setup.

Speed doesn't kill but this is the arrow setup I want, it is as dead in the hand on the shot as any other bow, the bow draws butter smooth and feels like much less draw weight, and it's the quietest bow I have ever shot (with no string silencers only OEM suppressors and STS). If 290+ fps when at 50 grains over IBO specs isn't fast enough for someone to kill a deer then 400fps isn't gonna be fast enough either.
