To make blanks all you need is some combustable wadding (cigarette paper), FFFG powder, and caps. Put some powder in the cylinder and one or two lwyers of paper for a wad to hold the powder in, cap and fire. You should get some but minimal discharge from the muzzle. You will get some discharge just from the powder, so be very careful with these blanks. The discharge will be adequate, at close range, to shread or blast a hole in a legal pad. They should never be shot at anyone for any reason.
