That way you'll have more powder flying out to break the balloon. For competition I want a load that has slightly more kick to it, and possibly better pattern. I put about a quarter or a third of an inch of a mixture of 4F black powder and Bullseye powder in the bottom of the shell as a kicker. The 4831 is a very grainy, slow burning powder that will not burn up before getting to the balloon. I then place the wad sticker on top.
Every shooter has their own competition load recipe.
This just happens to be the one I use. By the way, most shooters in the sport use standard primers in blank loads, but most people drill out the flash hole in the shell case primer pocket. A ruger Single Six makes the best wax gun. If a shooter is only going to own one gun then go with a .45 since you can shoot both wax and blanks. Then a .38 barrel is installed so that the wax can travel through it.
