I just purchased this bow wanting something light for hunting out of a harness. I wondered how it would stack up against my Zulu Scout as far as shootong my heavy 18" 2219 shafts. They weigh in at 516 grains. Shot three of them this morning. It averaged 307 fps. 5 fps faster than my Zulu Scout. I was pleasntly surprised at the power and noise suppression. I don't think I have ever heard a quieter crossbow.
