According to the archery program, with your set up

Legacy 254 fps

Extreme solo 261 fps

I have played with this program alot and I find the numbers to be off by about 5 fps low.

so I would agree with CBM SC. About 260 from the legacy and 270 from the Extreme.

I shot both bows before buying the legacy. I am shooting a 340 grain arrow with a 29 inch draw and 70 lbs pull and I get about 300 fps. This is what I shoot in the local 3D shoots.

I am hunting whitetails with the heavy CX terminators that weigh in at 460 grains. They shoot 258 fps.

Just a little info. Hope this helps
