I have used the Win/Nosler partition gold factory loading in 44mag to kill a 200lb black russian boar. The 250gr bullet penetrated the cartiledge shield and was recovered on the off side weighing 231grs.
I believe the loading in .45 colt uses a 260gr bullet and this load should level any black bear walking. The Speer gold-dot factory load is also another good one that is bonded and tough.I would use either for elk,(in a carbine) under 100yds.Hard cast bullets also are pretty good for bear and should penetrate at least 30 inches.
