Shooting Z3 64# 28” draw with 28 3/4” XX75 4” plastic vanes 125 grain field point at 238 FPS. Does that sound slow or about right?

My 62# Hoyt shoots my 30" xx75 2314's and a 100gr head (502gr total) through the chrono at 250fps. Hope that helps.
If your arrows weigh 500 grains, it sounds about right. Your setup should shoot a 400 grain arrow around 270 fps.
