I've got the Bowtech Carbon Knight. I'm drawing 30.5" at 70 lbs. My arrows weigh in at 8.7 GPI, 100 gn tip. I do not have access to a chrono. Does anyone have a ballpark of about how fast my bow is shooting from experience with their own? The IBO is 330, so I was thinking somewhere in the low 300's maybe?

The carbon knight that I shot for awhile earlier this year was set at 29.5" 68lb shooting a 386gr arrow at 312-315fps................. I would think that you should be getting 320fps out of your setup, BUT no two bows are the same........

Depending on your total arrow weight,(I assume around 400-410 grs) should be somewhere between 312 Fps- 317 Fps

They have calculators online to give you a good idea if you know you're arrow weight. My CK is at 60#, 27.5" draw and is at 286 fps with a 346 grain arrow.
