I am shooting the same w/ a 350gr GoldTip arrows and average speed is 274. Kicker is the bow shipped with the wrong limbs. ukey: Martin is shipping the 70# limbs out today. We'll see what I get when I can crank it up. Still, very happy w the speed.28" draw, 60 lbs, GT500 Ultralights 316 gr. = 265 fps.
