I've checked all the Meijer's, Wal-Marts around (Avon, Plainfield) and all I have seen is 22lr and .357, .380. Is there any recommendation as to day of week / time of day to check these places? Does calling in advance help? I did see 1 box of something weird at Gander in Castleton but it was like $35 !! Any info would be greatly appreciated.
