Well this should be funny.. my new Halon 32 5 with a 350 ibo and 75 rock mods doesn't like the broadheads I have I've shot 2 different broadheads montec 100gr and the freak nasty 3 blade expandables both are pin point accurate but they whistle really loud ...my arrows are cooking at 326fps my arrows weigh in at 418 grains total arrow weight . ... Anybody have any suggestions
