A sensor determines the spin rate or rotation frequency of a munition body of a guided projectile relative to precision guidance munition assembly. The spin rate is used to determine launch velocity of the guided projectile early in flight before GPS is operationally active. The launch velocity is used to determine whether a corrective maneuver is needed to change the range of the guided projectile. Logic can control the canards on the canard assembly in response to the determination that a corrective maneuver is needed.

A projectile and stabilizer therefor are provided. The sliding stabilizer is used instead of fixed or glued tail feathers, vanes or other fletching as a means for stabilizing projectile flight. The invention improves current projectile technology with reduced assembly labor cost, the elimination of bow clearance issues, improved accuracy with the consistent production of the sliding stabilizer, easy replacement of the stabilizer in the field, and improved projectile storage. A sliding stabilizer is designed to slide along the shaft of a projectile and comprises a circumferentially extending wing and a plurality of fins. In use, the stabilizer is positioned at the front of the projectile prior to launch, and the projectile slides quickly through the stabilizer until secured at a stop position at or near the trailing end of the projectile. An annular arrow fletch and arrow stabilizer are also provided. The annular arrow fletch may be used for; stabilizing arrow flight, providing better clearance and functionality then conventional fixed glued tail feathers. A stabilizer may be used with light emitting diode arrow nocks. The stabilizer may improve arrow shaft stabilization technology with reduced assembly labor cost, the elimination of facial and or face mask interference issues providing more clearance, improved accuracy, repeatable production with the consistent injection mold production of the annular arrow fletch, easy replacement of the annular arrow fletch in the field, and improved arrow storage. An annular arrow fletch may incorporate a metallic contact point, which will work with all light emitting nocks. A design of an annular arrow fletch may be affixed to an arrow by an arrow nock and may comprise an annular wing, a central elongated cylindrical cylinder with a cap and a plurality of fins with micro-groves and a metal contact. In use, the annular arrow fletch is affixed at the aft end of the arrow by an arrow nock prior to launch.

Ammunition cartridge comprising a rigid casing including a tubular sleeve and a base closing an end of the casing, a projectile mounted at another end of the casing, a propellant charge contained inside the casing, and an ignition device. The ignition device comprises an ignition charge arranged to ignite the propellant charge at a point of ignition distal from the base and proximal the projectile.

When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for small game hunting, pistol crossbow fishing, recreational shooting and competition shooting. The major fault of the standard bolt commonly used with a pistol crossbow is, they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, because of their irretrievability from any commonly used target, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Standard pistol crossbow bolts do not have a nock. It has two ROUNDED WINGS and a stabilizing TAIL which creates an accurate and stable bolt flight. No other pistol crossbow bolt has rounded wings and a tail. These features allow this bolt to be easily viewed in flight. The shaft has a THREADED TIP to accept almost any type metal point. The major advantage of this new bolt over other patented bolts of this size is the rounded wings. The rounded wings gives this bolt added body weight. This added body weight requires additional point weight to balance with that heavier body weight. This heavier bolt body gives this bolt the added weight needed for knock-down power in small game hunting and, the necessary added weight for better water penetration when used for pistol crossbow fishing.
