In addition, it is pertinent to note that the rifling marks present on both bullets are identical, yet one of the bullets does not rotate when discharged. Provided the assumption that the velocity of the bullets at the point of discharge is equivalent and that both are aerodynamically stable, it follows that the rotational force generated by the rifling in the first bullet consumes a portion of its kinetic energy. Consequently, there is an increase in the drag experienced by the rifled bullet as compared to its non-rifled counterpart. Moreover, it can be inferred that the absence of rotation on the second bullet results in a more laminar flow, causing less distortion of drag and leading to lower drag values

Humans possess olfactory abilities akin to other animals. It is widely recognized that the scent of a newborn is distinctive and recognizable to most individuals. Although humans have evolved differently in this regard compared to other species, it is plausible that our sense of smell still serves a purpose that may not be consciously acknowledged.
