You might try tuning the bow up a bit. Its amazing the difference that can make.
I was disappointed with numbers similar to yours a few weeks ago, but I'm shooting close to 260fps ( Saber @~55#/30" ) now.
Also, a few things struck me as odd about your post. First of all IBO means 70#/30" with 350gr arrow. If you're shooting 60#/27", well thats not IBO by definition. On a related note a 400 arrow probably refers to the spline/stiffness not the weight, so I think maybe you might be expecting something unreasonable about your arrow weight and its speed. But if not, well a 400gr arrow with 100gr head - well thats quite a bit heavier than 350gr IBO so if those numbers are to be believed it might not be surprising if you are shooting slower than you expect.
Read somemore of the post and topics on this forum and I'm sure you'll have it figured out it no time, its not really hard - I just started a couple of months ago myself.

sorry i am a newbie well im shooting an o9 firecat at 27 draw set at 60lbs im shooting a 100 gr feild point and a beeman carbon arrow 400 bow is being used for hunting its brand new and all just tuned up
i think your arrow is closer to 390 grain, slower it will be. im at 65#'s with my 2010 firecat. next trip to the shop and im chrono myself

If you want to get a IBO type speed you need to shoot 5 grains of arrow weight per each pound of draw weight, so with yours set at 60 lbs you can shoot a 300 grain arrow total weight including tip. With your draw length at 27 you have lost 30 fps right off the bat.
I agree that the Beman 400 is probably about +/-380-390gr (length??), but so called "heavy" arrow or not, 217fps seems awfully slow for what a Firecat should do............could you have been a typo meaning 271 and not 217?

i wish shot 12 arrows through all came up 217 216 seems real slow to me
chrono must be a doozy

217 is a little slow but with such DL and with a heavy arrow that's not so surprising. The bow must be tuned good and the arrows too.
