I’ve killed one old bull elk with the 150 Ballistic Tip from a 7-08. My first choice was the 140 Accubond, but my rifle shot the 150 NBT significantly better. Had the 150 NAB been available I would have been happy with that too. I really can’t see a need for anything heavier than a 150 in the 7-08/7x57. My friend Dober who used to post here liked the 150 NBT from the 7RM and Mashburn for everything, including elk. I believe he took his biggest bull with the 150 NBT from the 7 Mashburn. It works.
