just got a slayer se. 70 lbs limbs maxed out, NOS C cams, about 28.5 on the draw, everything is in perfect timing, using a 350 grain arrow I can only get about 288 out of it. IBO is like 325, given the draw is a little short of 30 i can see it being slower but I figured I cound get in the 300-310 range. can someone help me out ??? any help and info will be very greatly appreciated!!! thanks, Dave.
