I had my bow at the range getting ne rest and sites put on.i asked if I could use the chrono to see what kinds of speeds I was getting.I shoot a Hoyt Magnatec at 72 pounds with Gold tip hunters and I was averaging 269 so that is my soeed for my bow.I also use 100 grain thunderheads .The guy at the shop said I have a great bow and the speeds were awesome for it.I was 5fps faster then his Amthews legacy shooting the same arrows and broadheads.
