I have the same revolver and shoot basically the same load. The 3 APP makes you able to shoot countless times without breaking the revolver down to clean it. I think my flask only throws 20 grains, which for target shooting is plenty. As for your silhouette targets, those are a great way to judge your shooting skills on a man size target. We used to use the exact same ones both in practice and competition. The video made it look like you were shooting almost 25 yards I am guessing. That is good shooting off hand for that distance.
The video camera you got does a real nice job. It really has a good audio too. Nice Video.
