Have you got any of them left?

Assuming that they are black... Look at the bottom of the sabot in the powder cup. Does the cup have sort of a stair step effect on the inside wall or is smooth cup with a small production tit right in the center of the cup?

Or... on last option - on the outside of the petals, are the petals smooth or do they have shallow ridges?

How did they load for you? To tight - to loose or just right
