And I thought I was stupid. In all these cannon fail videos they are measuring out powder by the ounce or the inch. “Well we just put in 3″ of pyrodex….” WTF? 1200 grains is less then a cap full and is sufficient to lob a 1 Lb. projectile 1/2 a mile out of a 3″ bore. To top it off these geniuses made it out of PVC with cinder block reinforcement.
