I'm shooting a pse bow madness, 70# 29" What would be some good arrows to get and what spine ? 100 gr broadheads or 125?
I personally like a heavier arrow for a hunting set up...something over 430gpi total arrow weight. With a heavier arrow, the arrow absorbs more energy from the bow which gives you more kinetic energy. It also helps quiet your bow down some.
If you use a 100 grain head you'll need a 340-350 spine. If you want to use a 125 grain head then you'll need a 300 spine. It's a good target of 6-8 grains per pound for basically anything in north america. If you shoot 70 pounds that would be a minimum of 420 grains. To find the arrow, simply do a few very minor calculations: 1. The weight of the insert 2. The weight of the knock 3. The weight of the fletching (blazers=3 grains each, quickfletch=28 grains) 4. The weight of the shaft (length x grains per inch) For a higher FOC you can add weight to some inserts. To do this simply cut a bolt down, weights are too expensive.
