I tend to buy a case a year. With small game, plinking and silhouette matches and practice that's about right with a couple bricks left over. I try and buy at the end of the season so next seasons case arrived in Oct.
I'm lucky that my Cooper and the CZ's all like the same round so I can buy just once.
With this buying I'll likely start looking in the summer vice the fall to see if I can find it.
