33.4 A real case: the ammunition selection matrix

All the statistics in this chapter can be taken in hand in an operation every serious shooter performs at least once for every rifle: live-firing ten or so different loads and measuring their groups. Table 33.9 reports the real result of a test on a .338 precision rifle, with five-shot groups measured center to center, in two columns that, read together, say more than any theorem: the precision of the complete group, and the precision you would get by dropping the worst shot.
