Depends on capability of gun, sights, you, and where and how you hunt. I am currently using a savage 220 too sighted in at 100 as well, Burris ballistic reticle scope allows easy progression in range out to 200 which I have practiced at as we'll. Only one deer with it so far and that was at 40 yards. Wouldn't even consider shooting my 870 past 100 especially with open sights.
