Rainel Activ more info in the link https://www.google.ca/url?sa=t&rct=...tivhulls.htm&usg=AOvVaw0xCeslG4sBZ5nRlZWs5k8g. that particular shell I am not sure what it would contain as I have never seen one with a rolled crimp and a cover card . as above could be a slug or perhaps a dog training poper . shot lots of them loaded with number 4 and 5 lead for waterfowl ( when lead was legal ) but all had a traditional 8 point crimp .
Hold it up to a bright light you just might be able to see if it is or isn't a slug or buck shot . I don't think they came in any thing other than water foul or sporting clay shot sizes . The shell casing were prone to splitting ( primer pocket to the rim ) I have an example that has a reinforcing ring around the extractor rim in a stop gap measure to rectify the splitting .
I have some and they were all printed with load and shot size when factory loaded, and had a star crimp. I bet yours is a handload, and could contain anything. As mentioned previously, hold it up to a bright light so see what's inside.
