I have found out some more information on these rounds that I previously spoke about. They are NOT FN but they are FM, which I believe is Freedom Munitions. Problem I have encountered is there is not much information on this manufacturer and they do sell remanufactured rounds, basically reloads. I have included a photo, (best I could get) of the round. You can see the inner sleeve if you look closely from the head of the round to approximately 1/2 of the casing itself. Take a look and let me know your opinion, please.

Had a heck of a time trying to get this pic but if you look closely, you can see the inner shell. Sorry, but it's the best I could do.
