While cleaning the house out, we came across some guns and ammo in Pawpaw's closet. Nice Winchester-97 12-gauge pump open-choke duck gun, still had a hunting license from 1927 tucked into the stock behind the butt plate. There was a .22 rifle, and an old German bolt-action rifle with a broken-off trigger and the barrel sealed, probably used for drills and marching.
There was a brick of Monark .22 ammo -- a brick being ten boxes of fifty rounds each -- up on the closet shelf. I wound up with that and the guns. This .22 ammo was made in Minneapolis, probably in the late 1940's or early 1950's.
I figured the ammo, after sitting in a Louisiana closet for thirty or forty years was probably bad, so I took a box to the range to try. I think I had one dud, the rest shot just fine, so I stuck the rest of the brick in a lockbox.
Poking around on the net recently, I came across an antique ammo collector, and a little more research showed that this stuff was selling anywhere from five to twenty dollars a box, depending on the condition. Worth more if you have a whole brick in the original carton. Could be worth a couple hundred bucks that way.
Thus making that box I shot up the most expense .22 ammo I ever cooked off ...
