This ammunition came on the US market in the spring of 2006 and quickly sold out, primarily due to the stripper clips that are packaged with it.  The packaging itself hints at a history that is more interesting than the ammo itself.  At least two types of crates were used, each containing 540 rounds.  The original markings are stenciled over with the words "Ministry of Health, Nicaragua" in Spanish and a large white cross.  It's surmised that this ammunition was sent clandestinely to communist forces in Nicaragua during the Cold War disguised as medical supplies.  Each crate shows signs of being opened, one of four packages inside being opened, and several individual boxes being opened and then resealed with tape.  From the condition of the tape it does not appear to have been done recently.  The ammunition itself functions reliably and although accuracy is not on a par with some more recent surplus, it is acceptable considering the age.  The original stripper clips are a tremendous bonus as they have been difficult to find and expensive when available.

Trajectory and Drop Graph (click on the thumbnails)
Notes on the graphs  The graphs above each represent two sets of data.  The red line is the path of the bullet fired from the rifle with the sights zeroed at 200 yards.   The bullet exits the muzzle at a distance a fraction of an inch below zero inches.   This represents the height of the sight over the centerline of the bore.  The bullet rises above zero in a trajectory that then passes through zero again at 200 yards and continues downward.  The blue line is the the bullet drop in inches for the distance traveled.  This begins at the muzzle at zero inches and decreases with distance not taking sight height or zero distance into account.
