Shot placement, of course, however bullets on the soft side have field proven results, for example, before the 416 craze, most of the old timers who have seen dozens of bears killed (A.Runion and their likes) firmly knew a 270 375 slug was a better stopper than 300, this too, before wonder bullets. Big diameter bullets going 2400-2600fps with alot of lead and a soft front end is still sound advise.
