I didn't read everything in this thread, but the rifling induced spin's gyroscopic effect is far more influential than any "lift". Though crosswinds will make a bullet drift, mykeal's sketch shows that the projectile attitude does not change throughout the flight, unless there is a mismatch of bullet length and spin. If the barrel is pointed upwards, the projectile will land pointed upwards.
If the bullet is launched parallel to the ground, it will hit the ground downrange simultaneously with one simply dropped at the moment of launch, as the pull of gravity is constant on both. (32 ft sec/sec). Longer range and flight times are created by launching at an upward angle.
