Word of advice about Camp Perry...
Take along extra cash, if you can.
Commercial Row and the CMP Store is paradise for the shooter. You'll see boatloads of stuff you just can't live without--and some bargains that you won't want to pass up.
Example: 2001, National Pistol Championships. Federal Gold Medal Match, .45 ACP. Retail, about $40-45 a box, if you can find it.
CMP price? $15.00 a box!!!
Good luck! Oh, and if you want advice about your Springfield M1A, just ask them--they usually have a building full of goodies--and some of the most courteous sales reps and gunsmiths in the world there.
