So I put my first production lot into practice yesterday and they worked well. Slightly difficult to speed load fast, slight low point of aim, other than that only one problem. I must have not corrected one of those deformed pieces of brass, or it got mixed in. I speed loaded this batch of 6 and the cylinder would not spin. Thankfully on impulse I swung out the cylinder and dumped them all. It worked out, I completed the round.
Yes they were smoky.
What powder works well and is not so smokey?
