Roman was told to steal the dust, not steal it then use it. Though, he did use a bit of it. He threw a dust crystal at the rooftop and shot it, which would have seriously injured Ruby if Glynda hadn't jumped in to protect her.

And different amounts of dust in the bullets themselves. Some will have more of a payload, allowing elemental effects to happen. Others only have the amount needed to propel it, leaving it as a standard projectile.
