It wasn't until I read the above post that I noticed Federal Champion on the list.
I DO have a box of WM5233 (Federal Champion 230 gr FMJ, WM=WalMart). So I just now took a close look at it. My primers are not brass. They're the silver color of most primers. My lot number is not where your picture shows it, on the box flap. Mine is on the back, above the UPC symbol and the velocity chart.
But, after inspection, mine is not within the number range of the recall. Just normal (cheap) WalMart ammo.
My carry ammo for my little Kimber is PD45HS3H (Federal Premium 165 gr Hydra-Shok Personal Defense Low-Recoil), so no concern there.
