Blackhorn 209 vs 777 vs Goex Black Powder
Pulled this off another site..
I know guys like to obsess over 'velocity' when shooting so here is a good review of three of the most common powders used for shooting 'Smoke Poles'...

As you can see, every single Blackhorn 209 and 777 load produced higher velocities (150-500fps) than comparable loads using Goex black powder.
The Goex black powder was also the dirtiest propellant I used in this test by a long stretch.
777 (of all types) was better, but still relatively dirty with the 777 FireStar pellets producing the least fouling of the bunch. Blackhorn 209 produced significantly less fouling than both the 777 and Goex black powder.
At the same time, the Blackhorn 209 and loose 777 loads were comparable in performance with a difference of approximately 100fps in average velocity.
However, both Blackhorn 209 loads had BY FAR the smallest standard deviation out of any load tested. Since standard deviation quantifies the amount of variation in a data set, this means that Blackhorn 209 produced the most consistent velocities.
