From Ammoland:

Fortunately, an effective delegation from the United States was responsive to many of our recommendations throughout the meetings and was successful in their arguments to water down most of the most egregious provisions contained in each of the five draft reports the OEWG produced.  This included removal of attempts to require “individual” end-user certificates, ensuring any calls to regulate the undefined term “stockpile” were limited to those held at the national level, and for language requiring the marking (serialization) every round of ammunition to be amended into simply something that should be “consider[ed]” for ammunition under national ownership.
