Instructions:
      The Blastcap is simple to use and set up. It was designed without an Ematch feed hole in its side for 2 reasons; one, fishing the Ematch wire through the hole is tedious and two,100% of the black powders force is aimed in the desired direction as a result.
  • Position the Ematch in the Blastcaps bottom.
  • Add the desired amount of black powder.
  • Bend the Ematch wire over the top and down the Blastcaps side. Be careful not to crimp the wire.
  • Top off with dog barf or wadding packing down the BP
      (just a bit) DO NOT over pack.
  • Wrap a piece of tape around the top of the Blastcap and   over the Ematch wire. Let a portion of the tape overhang on top so you can fold it over to secure the dog barf and BP.

     That's it. Have a great flight!
