Someone may of already mentioned this. Practice from different yardages, also shoot from a sitting/kneeling position. If the bird happens to be super close, you may need to shoot a longer yardage pin. Due to your arrow not having time to rise yet. At close ranges, you may need to shoot your 30 or 40 yard pin. Also pay attention to your stabilizer while drawing in a blind. Lots of birds get spooked when drawing in a blind and the stabilizer hits the front of the blind. Maybe even take it off. Check out the Tom o hawk broadheads also. Those guillotine heads usually tend to flare past 20-25 lbs, unless you turn your bow down.
