We perform no-core full configuration calculations for a set of light nuclei including 16O with a realistic NN interaction, JISP16. We obtain ground-state energies and their uncertainties through exponential extrapolations that we demonstrate are reliable in 2H, 3H, and 4He test cases where fully converged results are obtained directly. We find that 6He, 6Li, and 8He are underbound by about 600 keV, 560 keV, and 1.7 MeV, respectively. 12C is overbound by about 1.7 MeV and 16O is overbound by about 16 MeV. The first excited 0+ states in 12C and 16O are also evaluated but their uncertainties are significantly larger than the uncertainties for the ground states.
