For deer out to 150 yards you would not see much difference in the performance. However on Game bigger than deer the 35 Remington is quite a bit more gun. Bullets up to 200-225 grain are available for the 35 Rem. Its a good woods gun at short ranges for any North American Game and I have seen many Moose fall to the old 35 Rem. I whacked one with a 35 Remington Contender. Also Elk and Black Bear.
