WOW, you guys are pretty smart about this stuff. I just wanted to clarify something. I think the original post asked if the fired bullet actually rises, and the general opinion is that it does not, which I agree with. However, I have read in several long range shooting manuals that explains the rifling of a barrel does affect the point of imact, but does not impart enough force to make the bullet rise, and for a short period of time, offset gravity. What the books clearly say is that over longe ranges, rifling will impart enough "spin" so that the bullet path is a slight arc (left or right) depending on the orientation of the rifling, so it drops from gravity and also drifts (although very slightly) at the same time. Does this make sense???

Thanks,
