  We present results of computer simulations of the diffusion-limited reaction
process A+B->0, on the line, under extreme drift conditions, for lattices of up
to 2^{27} sites, and where the process proceeds to completion (no particles
left). These enormous simulations are made possible by the renormalized
reaction-cell method (RRC). Our results allow us to resolve an existing
controversy about the rate of growth of domain sizes, and about corrections to
scaling of the concentration decay.
