Not all brass is at the same height - Lyman Bleacher Loading Blocks

the idea of making each row of brass at a different height is appealing because it more easily lets you load powder into a row of shells without thinking did I do that row. anything that helps you in your reloading is a better product. also they dont take up as much room on the bench. the footprint is smaller than the flat blocks.

they do not work well for pistol brass though . the holes are deeper than many different pistol case brass.
