jOe, I don't need to post pictures. I've been using ten to twelve gauge inserts for years. When centered by the insert, many ten gauge extractors just barely grab the 12 gauge shell if the insert is ground away in the area of the extractor purchase. Unfortunately, this system will not work with an eight to twelve gauge insert. I have not had the nerve to try this with my eight to ten inserts. I think it would work but I don't choose to grind the rims away on these.
