just got an email today from Orest Michaels at Civilian Marksmanship Program which says in part:
CMP No Longer Issuing Ammo at CMP Matches. The CMP will no longer issue ammunition to competitors for the Garand, Springfield, As-Issued Garand, Carbine or any other CMP matches. This includes the National Matches and all Regional Games Events (Eastern/Western Games, Oklahoma Games, Georgia Games, etc.). Competitors may purchase ammunition at the match or bring their own. Ammunition will be for sale at all CMP matches to all match competitors at a special discounted match price. For the 2012 National Rimfire Sporter Match, Lapua will donate 50 rds of ammunition to every competitor. Competitors will be responsible for bringing or purchasing additional ammunition to complete the match. Please contact the Competitions Department at email@example.com if you have any questions.
