When you go through in-processing and pick up your packet and scorecards the CMP issues ammunition for any Garand, Springfield, M1 Carbine or Vintage matches you are in. You get two boxes of 20 rounds for every match. The M1 Carbine folks get one box of 50, (Lake City). Even if you are shooting a Swede or a K98 in the Vintage match they give you two boxes of 30-06.
We shot Lot-2043-HXP-77. I didn't hear anyone have much good to say about it. I couldn't get it to group with my Springfield 1903A3 or Ricks Garand. Both are pretty good rifles. Justin Utley couldn't get a score out of it with his Garand or his Springfield when we shot on the same firing point either. I saw a tracer out of one of his rounds.
All of us are NRA High Masters and Distinguished Rifles. When I switched to my K31 in Vintage Rifle that afternoon on the next range over I shot a 100X4 to get started on that match using Swiss GP 11 ammo. With HXP I think I shot a couple of Xs the whole match.
Bottom line: This lot isn't much good.
