I did remember Sinister talking about the Sierra 77gr MK ( weird the things that a mind can retain !?

"Sinister
The Navy issued HSM 77s (Sierra Match Kings) to us at the 1999 and 2000, and I think 2001 Atlantic Fleet and All-Navy Championships. We definitely shot Black Hills 77s in 2002.
I bought 1,000 rounds of HSM (Orange Box) at Champion's on Commercial Row at Camp Perry at the 1999 National Matches and it shot very well, very accurate, no problems at all.
HSM 77s came in Orange Box, virgin components, 20 per individual box, 500 per long cardboard box, two cardboard boxes per case.
I shot them in a National Match M16A2, 1-8 stainless Douglas/Merchant barrel.
At the LANTFLEET and All-Navy all shooters fire at 200, 300, and 500 yards.
Got a Silver Excellence-in-Competition Medal at the 2000 All-Navy and a Bronze EIC Medal at the 2001 Atlantic Fleet. 1st Gold at the 2002 Atlantic Fleet and 3rd Gold in the 2002 All-Navy."
