Real or fake?
I vote “gun show” load. Not remotely DOD type class round
A key indicator here is “RARE…NOT NORMALLY AVAILABLE”.
Maybe the sign should read “…NOT NORMALLY AVAILABLE EXCEPT AT GUN SHOWS”. :-)
At least they are affordably priced.
This was bought by a buddy of mine for me ( I give him $10-20 to buy random cartridges for me at the gunshows he goes to w/o me ) from a guy at Market Hall in Dallas. Goes by Mellenchamps or something to that effect. He self printed some sort of 40mm book (he’s a printer by trade).
He was selling Greener police shotgun cartridges for $4 ea next to these in very good condition, for reference.
