I shoot dragoons in my CAS matches. I have to hold a little over a foot low in order to make solid hits.
I worked with reduced loads using Cream of Wheat as a filler and got some really accurate loads at 20-25 ft. using 25g of fffg and round ball.
These all hit in palm size groups shooting two handed unsupported standing.
I don't use this load only because it is time consuming to load them at a match.
I've also toyed with the idea of putting on some oversized front sights but haven't gotten past the thinking stage.
