This fall will be my third year in bowhunting (sure wish I would have started earlier in life, it's a blast!). Anyway, I practice with my bow quite often but I've reached a plateau of sorts. My groupings are not as tight as I'd wish. I don't have a problem hitting within the "8-inch pie plate" at 35 yards but I usually have a couple inches seperating my arrows. Even at 20 yards, my groups aren't all that tight. Does anyone have any advice on how I can get tighter groupings?
