### Abstract

We carry out a high-precision simulation of the two-dimensional SU(3) principal chiral model at correlation lengths ξ up to ≈ «4×10^{5}, using a multigrid Monte Carlo (MGMC) algorithm. We extrapolate the finite-volume Monte Carlo data to infinite volume using finite-size-scaling theory, and we discuss carefully the systematic and statistical errors in this extrapolation. We then compare the extrapolated data to the renormalization-group predictions. For ξ≥10^{3} we observe good asymptotic scaling in the bare coupling; at ξ≈4×10^{5} the nonperturbative constant is within 2-3% of its predicted limiting value.
