A first person narrator can, in some cases, be a foil to another character, but it is rare. Usually characters that are foils are foils to the main character, as they help to strengthen the perception of the main character through existing as his or her opposite.
A foil to a character is another character who acts in an opposite manner or has opposite characteristics. Foils help to show the strengths and flaws of a character through contrast.
You have asked a question that can't be answered. There is no such thing as an "average" bullet. Define what you mean by "average bullet" and maybe someone can help you.
Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared. Knowing the trajectory of a bullet points you in the direction of its origination. There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.
Well, genre maybe hardcore such as bullet for my Valentine. I'm not 100% sure don't get mad at me im only trying to help people.
Forceps and possibly the spot where the bullet penetrated the skin

When a hollow-point hunting bullet strikes a soft target, the pressure created in the pit forces the material (usually lead) around the inside edge to expand outwards, increasing the axial diameter of the projectile as it passes through. This process is commonly referred to as mushrooming, because the resulting shape, a widened, rounded nose on top of a cylindrical base, typically resembles a mushroom.The greater frontal surface area of the expanded bullet limits its depth of penetration into the target, and causes more extensive tissue damage along the wound path. Many hollow-point bullets, especially those intended for use at high velocity in centerfire rifles, are jacketed, i.e. a portion of the lead-cored bullet is wrapped in a thin layer of harder metal, such as copper or mild steel. This jacket provides additional strength to the bullet, and can help prevent it from leaving deposits of lead inside the bore. Incontrolled expansion bullets, the jacket and other internal design characteristics help to prevent the bullet from breaking apart; a fragmented bullet will not penetrate as far.
