US Army's NGSAR to Be Chambered for 6.8mm MAGNUM Round?

Is the US Army pushing for a new high-powered 6.Xmm caliber with their new NGSAR program? Recently, the listing for the NGSAR industry day in December was updated with a document describing in part the agenda of the second conference. Scheduled for 9:45 in the morning in the document is a 15 minute long presentation on “Ammunition Data – Surrogate Projectile and Specs”, presented by Todd Townsend, David Charowsky, and Mark Minisi. Minisi’s name may not be well-known, but it will be familiar to astute students of recent wound ballistics literature: It was Minisi who developed the finite element analysis-based tissue damage model, which has been refined over the past decade at ARDEC through PM Maneuver Ammunition Systems (PM-MAS). Mr. Townsend is also likely representing PM-MAS, now under the leadership of Colonel Hector Gonzalez

This is the route taken in Russia, where in the mid-1990s was introduced several loads for the Western 9x19mm caliber, as well as a new but fairly conventional round, the 9x21mm, also with optional AP load.
