I have not wrote off using grease. I have said that when this happens invert the gun on a better rod. Protect the barrel however you see fit, I failed to mention that, thought it went without saying, and put more load on the ball than any conventional ramming would.Your reluctance to the grease gun and writing it off as a poor way to remove it when more damaging ways are recommended just baffles me.
It's just simpler as a first move and if a suitable rod is kept close by, say in a vehicle it might just save the day.
If all that fails then get the grease gun.
All this could be avoided with thumb started ball and patch combo with a good lube!
