So what does it shape it to make it more accurate?
You should all ready know that HP's are less accurate then round nose.
I do not see your Logic so far
My knowledge starts and stops at his add. Most of the cheap 22 lead I've shot has an inconsistent ruff look to it. I'm no smith, reloader (yet) or accuracy shooter, never taken calipers to them. My understanding is the tool is supposed to reshape the bullet and take out the .002 variance in size hence accuracy claims. The new shape (round to hollow, cup, flat) is for different expansion depending on game.
