Had a dry ball once stuck so bad that the ball puller pulled out lead filled threads.
Went to the air compressor and gave it a blast of 120 psi and the ball exited with some force.
I've never pulled anything that is really stuck with a ball puller.
I Have a good blow snozzle with rubber on the tip that helps seal it when I press it against the nipple, extreme cases I remove nipple and appy snozzle tip directly to the nipple hole. The story some one posted of the smith a pumping a stuck one out with grease sounds like the safest way(if messy).
For me iffin 130 psi won't blow it out something is MAJOR stuck.
