SSG Brandon Green Sets Stunning 500-33X NMC National Record

SSG Brandon Green USAMUUSAMU Service Rifle shooter/instructor SSG Brandon Green set a new national record this past week, shooting a 500-33X in the individual Aggregate, National Match Course (NMC) with metallic sights. Green was near-perfect in the 200-yard Rapids, shooting an amazing 100-9X. Green was shooting a Tubb 2000 bolt-action rifle chambered in 6XC. He set the new record using Norma factory ammo. Yep, this was factory 6XC ammo, right out of the box.

SSG Green is the current NRA High Power National Champion and Interservice Rifle Champion. He and the rest of the USAMU rifle team have trained hard for the 2014 season. Yet Brandon joked about his record-setting performance, noting that the record was shot with his “back-up” gun. On his Facebook page, Brandon posted: “500-33X NMC. Not positive, possibly a record [Editor: Yes it was.] Not too bad for a #2 gun.” Not too bad indeed, Brandon. Congratulations on this achievement. This bodes well for Green’s goal to win a second straight National High Power Championship at Camp Perry this summer.

Note: After setting a National Record with 500-33X during the individual match with his Tubb 2000, SSG Green followed with a 498 the following day using a Service Rifle during the team match. Remarkable.
