Heavy ammunition
General requirements
- Heavy ammunition (for use in heavy handbows, heavy crossbows, light handbows, or light crossbows) must consist of a tubular shaft and approved head.
Tubular ammunition shafts
- The shaft must be constructed of HDPE pipe from materials meeting ASTM D2239 (minimum of 1 inch (25.4mm) inner diameter) or ASTM D2737 (minimum of 1 1/4 inch (31.8 mm) outer diameter) and manufactured of PE3408, PE3608, PE3710 or PE4710 resin, or equivalent. Either 100 or 125 PSI is approved.
- The tail must be left solid for at least 1 inch (25.4 mm). Cuts are allowed to be made beyond that in order to install fletches, if desired, but must have holes drilled at the ends of each cut to keep the cut from spreading. The tail is allowed to be slit if a 1 inch (25.4 mm) or longer section of HDPE pipe is reinserted at the end and laced in place.
- A nock is allowed to be cut into the tail end but must not be deeper than 1/2 inch (12.7 mm).
- Wooden nocks can be installed as long as they are securely attached by drilling and lacing with string.
Heads
- Regardless of the construction method, the head must be firmly attached by the use of tape and/or string.
- Head attachment is tested by pulling on them with a moderate level of force and twisting slightly. If the head shows signs of loosening, it fails inspection.
- Resilient padding of at least 1/2 inch (12.7 mm) and at most 1 1/4 inch (31.8 mm), after taping, must be added in front of the core of the head and be at least the same diameter as the head. This does not apply to tennis ball heads.
- The head must also have padding that provides progressively resistant give that extends from the tip of the padding to at least 1/2 inch (12.7 mm) over the core of the head that brings the total diameter of the head to at least 1 1/2 inch (38.1 mm) after taping. This also does not apply to tennis ball heads.
Rubber stopper head
- A size #6.5 rubber stopper (nominally 34 mm top diameter, 27 mm bottom diameter, 25 mm height) is placed in the end of the tube at least 1/2 inch (12 mm) and is firmly attached.
Baldar blunt head
- Baldar blunts can be used by cutting the support fins away so that the blunt slides over the HDPE pipe and attaches securely.
- Any classic style of Baldar blunt can be used in this manner, whether 1 or 2-piece mold or designed for fiberglass or wood.
Crutch tip head
- A crutch tip is placed on the end of the tube such that it covers the tube at least 1/2 inch (12.7 mm) and is well attached.
- Ensure there is no metal in the crutch tip, as metal must not be used in ammunition construction.
Tennis ball head
- A tennis ball is placed at the end of the pipe and attached using tape and/or string.
- The ball must not be perforated as this allows dirt, water or other debris inside of it.
- Regulation tennis balls are allowed to be used as ammunition heads, as is, with the following restrictions:
- The ball must weigh less than 3 ounces (85 grams).
- The ball must not be covered in tape.
- Dyes or stains can be used to change the color.
