My brother-in-law bought a Garand and is looking for a supply of ammo for it until his 2-month wait is over on ammo from the CMP. Anybody have any they're willing to part with?

He was at a gun show recently and there was a guy there selling the same stuff the CMP sells for double the price. He's a senior in high school and on a limited budget and I'm trying to help him get a few rounds at a decent price so he can get out and shoot his rifle a bit.

Any suggestions or anyone have anything?
