This is what Goex says about their Reenactor Powder:
"Goex Reenactor is dedicated to and manufactured for the historical reenactor and the value-conscious black powder recreational shooter. Loading by volume charge as regular-grade black powder, this product is ideal for blank fire in Muskets, Carbines, Pistols and Cannon.
However, it is also suitable for loading in recreational round ball muzzleloaders, where it performs nicely at low pressures. With 100% black powder ignition, it is very reliable with every shot. Reenactor Gunpowder is value priced for every budget minded shooter pursuing living history.
Available in a 1 lb. canister."
And from The High Road site by Loyalist Dave on May 31, 2012:
"The formula is the same as standard Goex powders. When a powder run is completed, the process has leftover powder..., it is not floor sweepings. The company then combines the remainder powder, which is not screened and from different lots. It is a mixture of the remaining powders from 1Fg to 3Fg and as the granulations and lots vary, so will the velocities when used from a BP rifle or smooth bore.
One could, for example pour a 100 grain load that is 40 grains of 1Fg, 50 grains of 2Fg, and 10 grains of 3Fg..., and then pour a second 100 grain load and get 10 grains of 1Fg, 20 grains of 2Fg, and 70 grains of 3Fg..., and so the velocity would be different, especially with differing lots, thus making precise shooting of projectiles very difficult.
It is sold at a reduced price for living history events, as velocity doesn't matter with blanks very much.
It isn't "weaker".
It works in flintlocks.
For folks who are paying $23.00 a can for regular Goex when doing living history events and reenactments, the price of $11.00 or a bit more per can is nice. "
