This sentence is from a paragraph from the original post that was nearly a year ago:
................ Thought about Barnes, but will they expand at close range? .......
The content of this sentence tells me the person that was the original poster does not understand bullet performance, especially at "close range".
There is a ballistic myth believed by some that "the bullet was traveling so fast that it went right through the animal and didn't even expand." Just the opposite happens, the bullet impacts the animal at a velocity higher than it is designed for and the bullet will "over expand"; that is, fragment into numerous pieces.
At a very long range, after a bullet's velocity has has slowed to a point it is below the designed expansion velocity of that bullet, the bullet will not expand much or not at all.
