So I was having a conversation about bullet trajectory, and the guy told me that bullets rise after leaving the barrel. I replied, "negative ghostrider". He told me that his dad showed him this on targets from 100 to 300yds, and that after his dad "shooted", the targets showed the bullet higher at 200yds than the 100 and 300yd targets. The rifle used was a .270.
Now, I was, and am, just basing my argument off common sense geometry, that a bullet will not rise in flight. There should only be 2 things that effect the bullet in flight. And both of those, that6 I'm aware of, only force the bullet to drop. (air & gravity) Creating drag and drop. Unless the rifling somehow creates this 'bullet rise'...I just don't see it happening. If that were the case, the rifling could make the bullet turn corners.
Am I wrong? Is there such a thing? I'm no rifle expert. I've never even been a long distance plinker. no deer hunter. But I understand bullet trajectory. I think.
