  We use nonlinear kinetic theory to study the remnant dynamics and the
particle acceleration as well as the properties of the nonthermal emission from
the supernova remnant SN 1006. The known range of astronomical parameters is
examined to determine whether it encompasses the existing synchrotron emission
data. Given the present-day spatial extent and expansion rate of the object, it
is shown that the hadronic gamma-ray flux is very sensitive to the ambient gas
density N_H and that the existing H.E.S.S. upper limit requires N_H < 0.1
cm^{-3}. The strength of the amplified magnetic field downstream of the shock
is about 150 \mu G.
