I work in medical devices. I have a project under development that uses medical swabs for the dialysis market. Since its a couple million units type of project the vender flew out for a meeting.
Turns out the company that manufactures the swabs I’ll be using also owns Berger bullets. They put two and two together and came up with this: http://shop.swab-its.com/barrel-cleaning-swabs-c17.aspx
It’s a reusable foam Q-Tip that screws into a standard cleaning rod for barrel cleaning. Pretty cool – and they’re sending me samples so even better. They don’t have shotgun versions yet but apparently soon.
… and I use tons of Q-Tips for cleaning although now that I have a connection I may have to support them.
