What is a “brick “ of 10mm
500 rounds in one enclosed package.......is "generally" considered a brick of ammo. I suspect this originates long-long ago, as in the mid 1950's I was buying bricks of .22 rimfire ammo that contained ten boxes of fifty rounds. (worth noting they cost $4.25 a brick for Long Rifle, but we generally purchased "longs" for $3.99 a brick)
