I have a mathews switchback xt and put on a trophy ridge matrix 5 pin. I can't get it to ajust right . I start setting it and after 30 yards i need to drop it down and it looks like it's to low. I start over each time. also i have whisker bisket rest if that helps. I put every thing on myself. Can anyone help me please? One more thing started at 10 yards with great grouping of 5 arrows in about 4 inch square. And now it's all over grouping of about 10 inch square.
