Percussion sharps caliber change ?

[Erwan]

3 Pedersoli offers a brass case for their sharps. But there are two different stock numbers. How do you determine which one to order ? (I realize you have to order their mold blocks to cast bullets that will work with these cases. But I want to try these brass cases out anyway).

The different size between those brass case comes from the different base and length of the bullets: the longer brass tubes for the "classic" Christmas Tree profile and the shorters for the "modern" profile...
I have twenty-six of them (13 longs and 13 shorts) but that is only for the days I'm out of flax cartridges or paper cartridges, which is very rare.
The tubes are not a good solution, they don't contains the good charge of powder and require a hook to pull them out after each shot...
