the large calibers like the .44 mag and .50 will generally go through windshields that may not be penetrated consistently by the .357 pistols at say 40M. that is about as good as it gets for anti vehicle with a pistol... a 5.56 rifle is not a good choice either... 6.8, goes through the windshield well, but stopping the vehicle? I would say its not enough round.
I would say you need a general type machine gun, M60, M240, RPK, MG42... or more to really stop a vehicle consistently . A good full sized battle rifle in say 7.62X51 or more might get it done too. ( that is by hitting the engine compartment to kill the vehicle.... I would say a M2HB .50 BMG, or similar would be a better way to go.)
