Wonder why blanks are as powerful as they are. All you're really looking for is a muzzle flash and some recoil I suppose.
Couldn't you create that with a Black-cat firework amount of gun powder?
It takes a fair bit of powder to get muzzle flash, I suppose, though often that is added digitally instead. You won't get much recoil at all, if no projectile is fired. You can spot that in low budget movies, when each shot is followed by an impossibly-slow muzzle rise, when the actor manually jerks up the gun after each shot.
Target handgun loads use a remarkably small amount of powder. If a competition doesn't require some minimum power factor, you can load down pretty far. My competition .38 loads use less than 3 grains of smokeless powder, which is well under 7/1000's of an ounce in each cartridge.
