It's not a new tactic. We did it in lots of different conflicts - even some we were not officially a party to.

And yes, it is extremely effective - one or two rounds can make everything suspect.

I am wondering if this is just something someone caught on to, as opposed to being "breaking news".

stay safe.

I knew it was done in VietNam, and given the Soviet propensity to drop booby trapped toys and pens in afghanistan during their occupation, it would only be logical they had booby trapped ammo, rockets, grenades, etc.

Don't accept candy from strangers, or rounds you don't know the source of, or found rounds in the dirt at the range...obviously.

Be cautious about rounds reloaded by other individuals unless you know they are careful and consistent...

It's all obvious until someone loses a thumb.

David, Google "Operation Eldest Son" or "Pole Bean". SOG/SEALs did it in Vietnam. The Brits did it in Africa and Southwest Asia.
