Is this dangerous? (Answered, thank you)
While we were having a "tour of the grounds", her daughter found what appears to be a gun cartridge (pictured). Thinking quickly, our friend handed the cartridge to me for "safe disposal".
What is it?
If I rip it open, what will I find?
(It is about 70mm long, and feels hefty enough that it could contain lead shot.)
Thanks for all the helpful answers - pretty well confirmed what I thought I knew (except for the sabot!).
I'll keep it safe and dry until I have time to dissect it with the boys.
