BH209 is worth every penny. I dont care who shoots what out of a gibbs or any other rifle. For my rifles, bh209 IS the best powder you can get on the market. Blackpowder fouling is very heavy in my rifles (sidelock, flintlock, inline) at time i have to use a small hammer to tap the bullet down. In an inline, i got a bad crud ring with goex, even while using 777 primers. But with BH209, i get zero crud ring, zero problems. No breech plug Mods either
