General Disarray's recommendation would work, however it is most likely a grip thing, and its simply a very minor torque problem that only puts you out 3" at 40yards. It may however amplify things when you install the broadheads, if you have not already. The broadheads will plane more when torqueing the bow with your grip than do your field tips. Try this, use just your thumb in the belly of your grip, tip your hand up and look at it while reading this, and your fingers and hand should look like a capital "L". Put the belly of your grip on your thumb, between the web and the last knuckle and nothing else should be touching the grip. It will feel weird at first, but should solve any torque problems you may be having. This is my grip for my Bowtech. Do make sure your shooting with a wrist sling when using this grip, as your bow will hit the ground if done correctly without a sling. If your not using a sling, and your using this grip I've described and your bow does not hit the ground, then we've discovered your problem and your "grabbing" your bow during the shot and thereby knocking off the arrows flight. Now all that being said, if you already have your broadheads installed and are getting excellent groups at 40yards, they are just 3" left, then do what General Disarray said, especially if your trying to hunt at this time. You probably don't want to start changing your grip.
