hi there.. one idea would be in order for this project to work i thought up a method by mayby using a lazer on the gun to distiguest from the point of the shot to were to bullet ends up in ratio. This would need a high speed camera to catch the trigger point at activation in comparison to were the bullet ends (you guy!!!). we have seen previous coversations on this subject about using different bullets to achieve this curve. The high speed camera which two will be needed the first one will be directored at the target while the second one will be pointed at the gun barrel to dermine the exact time the bullet leaves the chamber barrel. As the bullet is released from the barrel you can determine where the bullet should hit if the bullet remains traveling stright or not.You would need semi transparent glass in the middle of the target and the gun, as for a more realistic result, so the lazer will be on the glass as well as on the target at activation point(stationary point). If the bullet hits the glass and the target where the original lazer marking were it proves that th bullt cant curve.

That still won't work.

If the bullet has a sideways component, it won't land where the barrel was pointed.... but it still won't be a curve. It's an angled straight line.
