I stopped my .22 addiction by buying five GI ammo cans as my "limit". This was during the "Great Ammo Shortage". I never realized how much they would hold, even in factory boxes......

I've been reducing my .22 stash this year. Most of it is $14.87 Wally World Federal packs. The good old days.
As my limit for the LCR, I got some of Plano's small ammo boxes, one 100 round and five 50 round. That holds 50 of my carry ammo, and 300 for the range. That should be a decent supply.
