With todays bullets there is absolutely no reason to use a 30 caliber bullet heavier than 180 grains. Even if I were to go after bears with a 300 I would still choose a bonded 180 grain bullet such as the Trophy bonded bear claw.

Of the ones you listed it would be a toss up between the 180 grain accubond and the 168 grain TSX. Which ever one shot the best would get the job.

Also do not over look the Trophy Bonded Bear Claw bullets and the Swift A-frame bullets. You won't find a tougher lead core bullet than these two.
