Tom---I used 180 grain round nose"Core-lokts" out of my 30/06 for several black bears I've taken here in Colorado. They were over bait--shots were about 50 yards. They broke the shoulders & did the job. IMO---the velocity of the 30/06 don't warrant the "premium bullet". The "core-lokt"--"interlock" type bullet were designed for the 06.
