Most trim-to lengths are actually right in the middle of the tolerance so a manufacturer has maximum room for error either side of it. If you measure new bulk brass you'll find home trimming is usually more precise than factory, so we can cut a little more, as some do in order not to have to do it again so soon, or a little longer, as some do to better grip bullets seated out long for single loading accuracy.
