Perfect product!!! - MTM Ammo Box .22lr 100-rounds

I use these for .22LR ammo storage after I measure the thickness of the primer part of the brass case. By grouping same sized primer ammo together, I eliminate "fliers", get tighter groupings and have great storage. To measure the primer thickness I use the Hornady lock-n-load .17 to .22 rimfire thickness gauge along with a digital caliper. Greatly improves target scores and the boxes keep the ammo clearly sorted for use.
