To determine what shell holder is used, a complete Shell Holder list can be found through here:

We do not have a complete list of all calibers compatible for each Shell Holder as the vast amount of cartridges on the market make it very difficult to list all of them.
If a Shell Holder is not found for the cartridge you have, it is usually because we do not have enough demand to warrant producing one as a standard item. This does not mean that a Shell Holder we currently produce will not work with your cartridge. Attached is a list of the Shell Holders we produce in order by size so you may move up or down according to your needs based on sizes you may already possess.
