Generally, bullets to not rise or climb after they leave the barrel. in fact they start t drop as gravity is affecting them. You sight in your rifle to compensate for gravity so if a bullet rises it is because the muzzle is raised beyond horizontal to compensate for gravity at distance. A bullet will not rise above the axis of the barrel. It is no different than a quarterback during the passing of a football. For a long pass he throws the ball higher than the sweet zone of the receiver to gravity will put it there when it reaches him.
