After trying all the mods I read about on forums... I still was not happy. A reprogrammed chargemaster running this mod, will be the fastest I've found, with the least amount of overthrows. You can "tune" individual straws for different powders, and change them out easily.
Insert mcdonalds straw all the way to the rear. Mark where the front of the opening is.
Use cutoff wheel or some other method, and make a slot in the straw half way through. The size of the opening can be modified to your preference and to work with different powders.
It will look like this.
Cut off the straw past the end of the dispensing tube. You can wrap the straw with tape at the end to "wedge" it in there if necessary.
This is much easier to accomplish repeatably than other mods, and can be easily tuned to fit different powders. You can go so far as to tune a straw for each powder, as it is very easy to change out.
