Digging through my books I found that the bullet for the Dragoon revolver was 32 to the pound (220 grs.) The bullet for the revolving Rifle was 28 to the pound (250 grs.) It was a heeled sugarloaf bullet, they were both shaped the same, with the rifle bullet a little longer. Eras gone by makes a mould for the Dragoon, this probably as close as you will get.
