The projectile (1) of claim 1, wherein said projectile (1) comprises three notches (2). 8. The projectile (1) of claim 1, wherein said projectile (1) comprises four notches (2). 9. A composite or polymer casing comprising the projectile (1) of claim 8 mounted therein. 10. A metal casing comprising the projectile of claim 8 mounted therein. 11. A box of composite casings comprising: one or more composite or polymer or metal casings in combination with the projectile of claim 8;a cartridge-holding device; andan outer box sized to contain said cartridge-holding device with the one or more composite or polymer or metal casings in combination with said projectile positioned therein. 12. A method of making the projectile of claim 8, said method comprising: molding or machining metal to form the projectile. 13. A method of using the projectile (1) of claim 8, said method comprising: positioning a composite or polymer or metal casing comprising the projectile (1) in a chamber of a projectile-firing weapon; andfiring the weapon. 14. A method of using the projectile (1) of claim 8, said method comprising: positioning the projectile (1) in a chamber of a projectile-firing compressed air weapon; andfiring the weapon. 15. A projectile (1) for ammunition, said projectile (1) comprising an outer profile geometry on an impact end portion (5) thereof, said outer profile geometry comprising three or four notches (2) equally spaced from one another and extending in an axial orientation relative to a dissecting axis (3) extending longitudinally through said impact end portion (5) of said projectile (1), wherein each of said three or four notches (2) (a) comprises notch surface portions (4,7) so as to increase (i) an overall outer surface area of said impact end portion (5) of projectile (1), and (ii) a given length of an outer surface periphery (Sp) extending along a line within a plane normal to said dissecting axis (3), (b) has a notch depth dissecting line (Ldd) extending axially through and being located along a path that represents a largest depth within said notch (2), wherein said notch depth dissecting line (Ldd) has a J-shape or reverse J-shape as said notch depth dissecting line (Ldd) moves from an uppermost periphery portion of said notch to a lowermost periphery portion of said notch, and (c) extends a length substantially equal to a distance along said dissecting axis (3) from a projectile tip end (18) of said projectile (1) to a transition periphery (52) along said projectile (1), said transition periphery (52) separating said impact end portion (5) of said projectile (1) from a cylindrical portion (6) extending from said transition periphery (52) towards an opposite end (61) of said projectile (1), wherein said impact end portion (5) comprises a metal, wherein said metal is selected from brass, silver, lead, lead alloy, copper plated lead alloy, copper, or stainless steel. 16.
