I second that, not trying to sound like a broken record, and no I am not sponsored by Mathews but I do admit I am biased towards them. I am here to tell you that something is wrong, and I have no idea without seeing you and your bow first hand.So far the Drenalin seems to be more accurate than most of the Mathews hunting bowssimply because it balances so well in your hand. I wish I could spend some time with your bow, I am betting something is wrong with it, and not with you. If you can shoot any type of groups with another bow, then this new Drenalin should be a walk in the park. One of its best selling points is the fact that it is very accurate. I have not heard much go wrong so far, and out of our shop we are selling them like hot cakes. My best advice to you is to take your bow to a confident and educated Mathews dealer for a trouble shoot. I am no expert and I am still learning a lot, but in the three years I have worked ina Mathews pro shopI have set up and tuned more bows than I can remember or dare count.Just from purehands on experienceI now can see/find a lot of problems right offthat would have troubled mein the past with my own bow. Of course my friend/owner of the shop is a excellent teacher, and it totaly qualified as a bow mechanic with many bow manufactures. Hope this helps and let us know how everything works out. Just my 2cents. Jason
