So I ordered a new bow the other day and I’m starting to work up a new arrow. My goal is to be with a final weight of around 500 grains. This will be primarily used for deer so I know it’s overkill but I really like the benefits a heavier arrow can provide The bow will be a Mathews Halon 32 7 with a 31.5” draw so about a 30-30.5” arrow set at 56 lbs. I know arrow length is very important but I’m just kind of ball parking at the moment and I can’t get a final measurement till my bow gets here. I shoot 125 Slick Trick fixed heads. Been thinking a lighter 8 GPI arrow with a 75 GR insert would get me there but get kind of hung up on spine because of my relatively light draw weight. So what’s the best way to go about getting to that 500GR weight and a descent F.O.C. with a long arrow?
