Thanks. I think they're a cool tool, designed to do a job that is no longer really a big issue due to plastic shot cups. Seems to me they would still be great for removing plastic residue or hard to dissolve powder residue that has been left for too long.

I found a new in the box 16 ga. one on eBay a few days ago and bought it. I may just need it one day.
