For a bit louder blank you can fill the brass about 1/4 of the way with black powder or substitute like Triple Seven, put a small piece of tissue on top of the powder and compress with the proper size dowel stick. It will stay compressed. All this is safe and will be loud enough. I used to do it all the time in 44 Spcl cases for quick draw competition. DO NOT, however, EVER aim a blank at anyone. At close range, e.g. up to about two feet, the blast alone will blow a beer can apart...or you face.
