Stuffing cones has never been so easy; You simply fill the appropriate cones (you can find them here) into the RAW Six Shooter, add your favorite filling, close the lid and shake vigorously a few times - six joints are ready in no time.
It is also sustainable because it is now made from bamboo. 
The fastest shooter in the West is still Clint Eastwood, but you can pretty much secure the title for the fastest cone filler with the joint drum!
