If you were following the standard procedure, then yes, I think you had a defective one. If there was no filler, it could easily just run straight out the battery end. Or you were pushing the needle straight through the filler and filling up the atty and chamber. You only really need for the syringe to touch the top of the filler, or go about 2mm into it.
I've been filling mine with the 18g blunt syringe since yesterday. It doesn't even fit through the fill port, but I just cover the hole and fill slowly. I've found I can fit an extra .2 easily this way.
