I had .22 shells stockpiled but we have shot over 2000 rabbits this year and haven’t been able to easily restock. We look at Walmart but they never have any.
Just go to ammoseek.com and let your fingers do the ordering. It is a web site that lists the prices of ammo from different online sellers. It updates the links every couple of minutes, so it is very current. Since shipping is a factor in cost, buying in large lots is the best way.
