I don't call my arrows heavy, I call them what I require. I want my arrows 450-500gr. Weight for penetration and a flatter trajectory. I'm not planning my hunts on short range shots, so I'm not shooting a 600+ grain arrow. My arrows have a 42gr insert and 125gr tips, total weight 463gr. I have the penetration I need which was proven on my bull this year. I do have some 150gr tip I may shoot at a bear this year, still undecided. I still like to play with arrow weights and my chrono. Y'day I shot 3 weights with 2 different bows.
