I'd be willing to bet that somewhere, someplace a warehouse exists that houses seller's records showing that I purchased .22 cal rimfire match ammunition by the "brick" - late 70s and early 80s.

I'd also bet that the bet can't be proved one way or the other because the old handwriten records are not in a form that can be "data mined". On the other hand, those records may be in some landfill or gone up in smoke.

Not that it makes any difference because all of that ammo was expended on punching paper decades ago.
