Walmart near me is always spotty on ammo availability. I have seen the case empty for months and then full for months. I catch hell every time I buy another box or two of Federal bulk .22lr ammo. Have about 15 now and buy at least 1 when they have it. When we go to the range we can easily shoot a full box and I can remember when it was not in stock for at least 3 months in a row late last year and I had none.
