Question re: ammo authenticity/safety

[NMRMN]

I just opened up a box of ss109's I have , HS is FC 12. all primers are silver with blue color sealant on them , my 855's have a bronze color primer with purple sealant on the primers

No visible sealant on either the m193 or ss109 here, but the primers ARE crimped. So reasonable to assume per Hoot that they are likely commercial reman's and GTG?

A few years ago , Sportsmans guide was selling 1000 round boxes of loose 7.62 x 51 for cheap. I bought a couple boxes at the time and found out later from a friend who is a marine armour that they were de linked machine gun rounds that were found to be breaking the cases just above the rim when fired .

It was just one year head stamp that was the issue and only a few of those that were an issue, but due to those few failiers the government took them all out of service and sold them to the guide as surpluse ammo.

I shot a few through my CETME with the year head stamp and did find one out of 300 that cracked at the base.

These de linked rounds had a distinct color diferance where the belt link was at.
