Sometimes easier said than done.

In the 1970's I bought a box of CCI MiniMags every Saturday morning at KMart. Now there are no more KMarts.

I also used to buy them at 1 of 2 local gun shops. They are both closed.

Cabelas and WalMart are what's left. They have no inventory as we speak.

For all the dozens of bricks of bulk .22s I bought over the years, it may not have been "good", but it was good enough.
