The SU(2) string tension is obtained from measurements of Wilson loops on a 6/sup 4/ body-centered hypercubic lattice. A crude perturbative determination of ..lambda.. indicates that the results are consistent with those of the hypercubic lattice. However, the chi(2) loop ratio is found to follow the asymptotic-freedom curve for a much larger range of g/sub 0/ than has ever been observed for any hypercubic actions. This strongly indicates that the body-centered lattice may, for a given amount of computer run-time, greatly increase the reliability of nonperturbative calculations.
