I think the previous posters were correct and you'll be far better off with a minimum of a 7.5 grain per lb of bow draw weight and a 300-400 spine, but read the charts and get the correct spine weight, and don't try to use overly short arrows or fletching thats not sufficient to rapidly stabilize the arrows, check your game department laws
its been proven consistently in testing that the ideal broadhead DESIGN
should be approximately three times its diameter or blade width,
in length, and fixed blade generally out perform mechanicals
and blades should ideally be at least 1.125" in diameter or blade width,
at the widest point to maximize penetration and lethal damage
