Why not cast for deer? Make them sufficiently soft and they should work as well as cast does in a .30-30 or .303 Savage which I have proven to my satisfaction quite often. Something in the way of a FN bullet weighing between 165 and 190 grains can be moved at the same speed as a factory jacketed bullet. (I routinely load my .30-30's with a 190 grain FN cast relatively soft, 10-12bhn, at exactly 2000 fps out of a 24" barrel - squarely in factory energy territory, and with excellent accuracy and zero leading.)
