I have not expirienced this problem with them, but refrering to your comment about ducking the arrow, it has been provin that deer are more likely to duck an arrow at 15 or 20 yards as opposed to 30 or 40. I know this seems backwards, but the sound of the bow/arrow at closer ranges startles them more causing them to react faster, where-as with a 30 or 40 yard shot the sound comes accross more subtle which doesn't spook them as bad. I'm not tryin' to pick any bones here i am just imforming you so you can make a better choice about your problem.
