I always wondered where this term came from until about 25 years ago when I came across this cool little tool. It's use was to trim the top of paper shotgun cartridges so they could be rolled nicely. I have seen like one other in my life and it was on an internet site that has the most lovely tools in the world. If anyone has one would they please chime in as I am wondering if they came with the 10, 12, 16 and 20 gauge disc. This one is for 12 gauge.
