How does one adjust the trigger pull on an Iver Johnson 22 Model X rifle?

To adjust the trigger pull on an Iver Johnson 22 Model X rifle, first ensure the rifle is unloaded and safe to handle. Locate the trigger adjustment screw, typically found at the rear of the trigger assembly. Turning the screw clockwise generally increases the pull weight, while counterclockwise decreases it. Make small adjustments and test the trigger after each change to achieve the desired feel.
