Hey Jim; you are not the only one with that kind of problem. Makes for a right proper mess.
Border Collie: I use that method also but I do not loosen the end. I just keep pumping till grease comes out.
That is also how I get the original air out after a cartridge change.
Many times I feel the plunger spring gets weak and can't force the grease forward. Locking the plunger and pressing on it should get you some grease.
