Reloading 37mm Rounds

37mm Launcher

Aerial Star Bursts

You can make aerial star bursts in much the same manner that you made the smoke bursts. You just follow the instructions as per the smoke burst, but add your stars (flare pellots) and a small amount of ffg black powder to propell the stars. Here's the breakdown of the aerial flares:
Red Star           % by weight

Strontium carbonate       15.0
Potassium perchlorate     69.0
Charcoal, Air float        4.0
Red Gum or shellac         9.0
Dechlorane                 3.0

Green Star 

Barium nitrate            48.0
Potassium perchlorate     33.0
Copper carbonate           2.0
Red Gum or shellac         9.0
Dechlorane                 8.0

White Star 

Sodium nitrate            45.0
*Magnesium-100m or finer  45.0 
Nitrocellulose lacquer    10.0
*Adding 10-15% magnesium to the red or green mix will increase the candle power. Add Mg-to-NC lacquer before adding to mix.

You must moisten one of the above flare (Star) mixtures using denatured alcohol (not isopropyl) or NC lacquer solution. Once it is ready, you'll press it into a "shape" approximately 1/2" to 9/16" thick. Then you'll make a slush out of prime comp and NC laquer, and spread it on the top of the star comp "shape." Cut it into small (1/2" to 9/16") squares (use a very sharp knife or razor blade) and allow it to dry at least 12 hours at room temperature. Once the shape is completely dry, break it into individual pieces. Place the pieces into the top of your casing around the fuse, pour 3/4 to 1 full tablespoon ffg black powder and glue the top plug in place with adhesive.
