I need some advice on building heavy-ish arrows. Last year I half unintentionally built some rather heavy arrows (725gn taw with 21.4% foc). They shoot awesome and I can’t wait to try them out this year, but I went to a local 3D archery shoot and realized a few drawbacks to this setup. The biggest is the limitation to the range that I can shoot with the ezv sight due to the fact that 70lbs 28in draw bow only throws the arrows at 225 fps limiting me to 50 yards at the maximum. This is fine for where I hunt as my maximum shot distance might be 40 yards, but I am thinking about going out west and doing an archery pronghorn hunt and feel I need to stretch my shooting distance just a little bit. I want to maintain the 200gn IWSB broadheads from my current setup, but I can’t find any info on static spine calculations to give me a starting point for that much weight up front. Also I have a goal weight of between 550-600 gn taw but not hard set on the upper limit.
