We were just using our fingers to punch through the metal with maximum resistance before this bad boy came along. My father got his hands stubbed. My grand-father and his father before him all had stubs for hands too. We just took it in stride because that’s the way it was done and it wasn’t as bad as for us as it was our neighbours family- they were in the same trade, and all deaf. Then deafened yet again. Still, I was afraid I was destined to the same fate as my forefathers. Waves that resembled the ticks of a metronome more than a hello. Crestfallen children, I could never give thumbs ups to. A wife who mourned my lot so much she would barely be able to walk in the mornings — it was so sad.
And then this bad boy came along. You saved my hands. You have no idea the impact you’ve had on our lives. And the impacts you spared us from. Now that we’re actually penetrating. I think my grandma said it best. That’ll probably hurt less. It does.
The purpose of a hollow-tip bullet is to catch as much soft matter in the center, which forces the rim to mushroom outwards and damage more soft matter surrounding the path. This also "puts the brakes on" the forward momentum, so the bullet is not as likely to exit the back of the first target and thus waste energy on this target and risk hitting a second target.
The purpose of this armor-punching bullet is to cut a clean hole in the armor, without expanding or mushrooming. This lets the entire shaft of the arrow to sail through the armor with minimal friction, and it's more likely to hit the second target behind the armor with the maximum possible remaining energy.
I think it's not designed to punch through at all, but rather to compress the target area and deliver blunt trauma on small game. Only works here because the steel is so thin. Shoot it at a bag of sand and I'd guess almost all of the others go through deeper.
that's a contradiction. hollow point rounds are design for maximum expansion and maximum soft tissue damage, while sacrificing penetration. armor piercing rounds are FMJ, designed for no expansion, and maximum penetration, sacrificing everything else. if someone is marketing you armor piercing hollow points they're full of shit, and you should look elsewhere for your ammunition.
the arrow head your talking about, generally referred to as a small game blunt, is similar in theory to hollow point ammunition, designed to transfer as much of it's kinetic energy as it can into the first thing it hits, for crushing the skulls of rabbits and squirrels while not penetrating too deeply into the ground if you miss.

Never seen an arrow quite like the concave one with max piercing
