RE: Loud crossbow .
I have a 150# Barnett Ranger and a 180# no namer , I use cat whiskers on both , bow press not needed . I experimented with String Leeches(flew off) , Limb Savers(no noticeable effect) , and the Sims crossbow kit , none worked better than the simple cat whiskers . BTW , if the deer has time to hear you you're probably shooting from too far away . My slowest crossbow hits 215 FPS , from 30 yards or less the deer has no chance of hearing it .
