A projectile 1 for ammunition is disclosed, said projectile 1 comprising an outer profile geometry on an ogive-shaped impact end portion 5 thereof, said outer profile geometry comprising two or more notches 2 extending in at least one of (i) an axial, (ii) parallel or (iii) slightly inclined orientation relative to a dissecting axis 3 extending longitudinally through said impact end portion 5 of said projectile 1, wherein each notch 2 (a) comprises notch surface portions 4,7 so as to increase (i) an overall outer surface area of said ogive 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, and (b) is surrounded by an outer side surface 51 of said ogive-shaped impact end portion 5 of said projectile 1. In other words, the presence of the two or more notches 2 increases a length of an outer surface periphery Sp extending along a line within a plane normal to said dissecting axis 3 relative to the same outer surface periphery Sp extending within the same plane normal to said dissecting axis 3 when a notch is not present.

A projectile has a front portion, a divider and a cylindrical portion. The front portion has a wall defining an interior cavity, which is closed by the divider. The cylindrical portion comprises a cylindrical sidewall having an outer surface and an inner surface. The projectile also has a plurality of depressions in the cylindrical sidewall. The depressions have an outlet adjacent the second end, an inlet toward the first end and a neck area between the inlet and the outlet. A width of the inlet is smaller than a width of the outlet. The depressions at the neck area have a curved sidewall, but a generally straight sidewall between the neck area and the outlet. The surface of the depression extends at a ramp angle from the outer surface of the sidewall at the inlet of the depression toward the inner surface of the sidewall at the outlet.

A non-pyrotechnic aerial display apparatus may include a head portion and a wing portion. The head portion may include a front portion, a rear portion, and a plurality of channels extending from the front portion toward the rear portion. The wing portion may extend rearward from the head portion. The wing portion may include a top surface, a bottom surface, a leading edge, a trailing edge, a rear edge extending from the leading edge to the trailing edge, and an airfoil extending along the leading edge. The wing portion may include a counterweight. The apparatus may include one or more forward-facing lights. The apparatus may include one or more rearward-facing lights. Other examples may be described and claimed.

A magazine caseless weapon is disclosed and can be used for shooting using the caseless ammunition. The weapon includes a handguard or handguard with bipods, or gunstock, magazine, barrel, barrel latch, multifunctional cartridge, conical bushing of a receiver, the receiver, safety spring, safety, trigger guard with magazine box, trigger bar, trigger bar spring, magazine latch, axis, firing pin, spring of firing pin latch, firing pin latch, conical bushing of the bolt, bolt body, firing hammer, mainspring, mainspring latch, hunting or skeletal buttstock, threaded bushing for back plate screw, back plate or adjustable back plate, threaded bushing of bipods, cross screw, cross screw nut, upper screw, lower screw, caseless ammunition, dowel screw, dowel screw nut, latch of adjustable back plate, adjustable cheek piece, latch of adjustable cheek piece, stop, stop lock, threaded bushing of stop lock, lower part, upper part and screw of muzzle break, folding adjustable bipod, and bipod latch.

The present invention provides a projectile device and a method of manufacture of a projectile device and in particular, to a pistol bullet and a rifle bullet and method of manufacture of same. In one embodiment, the projectile apparatus has a cylindrical body portion having a diameter, a front nose section tapering from a most proximal point of the projectile to the cylindrical body portion, and a rear tail section connected to the body portion and extending to the most distal point of the projectile, in which the front nose portion comprises a plurality of twisting depressions forming troughs.
