or
pwm08 = 255;
(those being the extremes) and the servo turns a total of about 180 degrees.
The HiTEC HS-322HD servo has a range of travel of just about 200 degrees. You can take it apart and physically cut off its internal position feedback to make it act more like a motor, but then it wouldn't be a servo anymore.

If you want a servo with a greater range of travel, consider using a big gear on the HiTEC connected to a smaller gear on whatever it is you want to move to a specific direction.
