I realize that the major handgun calibers (9mm, . 40, and .45) all pretty much function ballistically the same... roughly the same penetration and expansion...given that a person is using premium defense rounds.
So.. if the rounds expands... its pretty much a wash because .1 inch extra expansion will most probably not make any difference. It's about shot placement anyways.
But looking at .40 vs. 9mm Gold Dot Hollow points... I cannot help but feel that the .40 round is more likely to expand due to the bigger HP cavity.
So... I'm not asking which one will expand to a greater size... but which of the two is more likely to fail to expand.. given that we are comparing the same brand of HPs.
From the same manufacturer/brand, would a 9mm HP have more likelihood of failure to expand than say .40?
It's kinda like seeing .22 JHPs. I don't think that they would reliably expand. The HP is too small to "catch" enough flesh to cause it to expand.
Anyone else feels the same?
