I am planning on buying a new butt pad for my BT to replace the factory Browning one, and am wondering what it takes to fit a new pad to the gun. With the shooting season about 2 weeks away, I don't exactly have time to send it to someone and have them grind it for me. Plus, I'd like to learn how to do it myself. So, any suggestions or pointers? (pad will most likely be a Kick-Eez or Gooey) Thanks, Josh.
