Goex "reenactor" powder is just the sweepings from the floor put into a can and sold to the unsuspecting.
While that may be the opinion of the poster as to the quality of the product, it is in fact not how the powder is made, and while it is possible to use "reenactor grade" powder for casual target practice it is sold for use as blank ammunition. No idea how the buyer could miss that and thus be "unsuspecting".
