First is your TP. .107 is huge. Go bck to the factory one at .081. You may get better performance by going even smaller. Second, try a "quality" domed pellet. Much as I love destroyers, they are not precision pellets. And lastly, slow the gun down to 700-750 and rerun all your tests with the pellets again. Find one it likes, then start runnig the speed back up.
