We study the SU(2) gluon and ghost propagators in Landau gauge on lattices up to a size of 804. A comparison with the SU(3) case is made and finite-volume effects are investigated. We find that for a large range of momenta both propagators are remarkably alike comparing the two gauge groups. In the low-momentum region we also compare to recent results obtained in DSE studies on a torus.
