Thick wall Beraq Tubes
Heavy wall Beraq tubes with end plugs.
The end plugs are set face down 6 or so at a time in a small puddle of Acetone to soften them then pressed in the tube with an arbor press gently. Tubes are only about 75% filled with comp and care taken on the closing end.
As in everything pyro refer to rule #1 ... keep your digits.
