Tubular Construction Standards

Strapping tape is a heavy duty filament-reinforced tape, usually used for shipping. 

The padding used on the tips and the side wraps must be Resilient Foam, defined by Society as dense, plastic, closed cell foam such as ethyl polymer.  

Stoppers must be inserted ½ inch into the shaft; modified Classic Baldars must be slipped ½ inch over the end of the shaft. 

NOTE: See the tutorial on making tubular ammunition for PHOTOS of the following steps. 

The tip must be secured to the shaft with ¾ inch to 1 inch wide strapping tape:

  1. At least two pieces of tape crossed over the tip in an X, with each end extending down the shaft at least 1 inch, Then,
  2. A wrap of tape around the junction of the tip and the shaft. 

The padding on the tips must be made from round pieces of resilient foam approximately the diameter of the tip.  (Square pieces create corners that can penetrate too far into a helmet’s grill.)  

The foam padding must be secured to the tip with ¾ inch to 1 inch wide strapping tape:

  1. At least two pieces of tape crossed over the tip in an X, with each end extending down the shaft at least 1 inch. Then, 
  2. A wrap of tape around the junction of the foam and the tip. 

The side wrap must extend from the tip of the padding to at least ½ inch down the shaft, and must be secured with strapping tape:

  1. One or more pieces of strapping tape must wrap all the way around so that the ends of the side wrap meet without a gap.  There must be enough pieces of tape to cover the side wrap from the top edge to the bottom edge.  Then,
  2. The side wrap must be secured to the shaft with several pieces of ¾ inch to 1 inch wide strapping tape crossed over the tip and extending down the shaft at least 1 inch. When complete, the entire head must be covered with tape.  Then,
  3. The ends of the crossover pieces must be secured with a wrap of at least ¾ inch wide strapping tape around the shaft as closely under the side wrap as possible. 

NOTE: The length of the side wrap must be at least 1 ½ inches (½ inch over shaft + ½ inch on stopper + at least ½ inch foam thickness on the tip).  If the foam on the tip is thicker than ½ inch, the side wrap needs to be more than 1 ½ inches long. 

NOTE- After covering the head with red duct tape, a wrap of duct tape around the shaft covering the ends of the strapping tape will help extend the life of the strapping tape.  Using duct tape with an unusual design or color for this wrap can help identify your ammunition on the field and after large battles.
