I dont know why no one ever told me this, but the air holes on the plastic bullets arent punched through !!!
I realized the carb on these isnt punched so they get no airflow(all 6 of mine were like that), just take a safety pin or something and poke it through then it works like a champ with just the lightest sniff.
Thanks to RiffChord over on reddit
I will try to post some pictures on this later.
I just took a sniff from my fixed bullet and it works, normal sniff, no back of the throat, all the snuff in the chameber is gone !!!
