Not sure if the stuff I traded to you was boxer-primed, but at least it was brass-cased. If it was boxer-primed, you could potentially reload some match-grade ammo yourself from the cases.
As for factory-produced... to get it by Sunday would be tough, but not impossible. I know that the last time I went into Ed's Surplus & Marine on 196th and Hwy 99 in Lynnwood, they had a box or three of Federal Fusion® ammo, but the advertisements don't call it "match" ammo, just really accurate hunting ammo.
Other than that, your best bet is to call around to local gunstores and pawn shops for their ammo stocks and ask them to hold some if you find they have some match ammo.
