We usually pay folks to sort our once-fired hulls to make sure that they are all in tip-top condition. With the state of the market we just can't do that right now. Our inspection team looked them over. We found a few dusty hulls and some flattened ones too. Maybe a couple twice fires. We strive to pull out any of the nasties, but things are moving fast these days. To compensate for this we have packed these boxes with a minimum of 525 hulls (5% extra hulls).
Hulls contain the same internal basewad as Winchester AA HS hulls.
