Dillon RL550 casefeeder will need a casefeeder plate as well as a casefeeder kit. These kits are what specifies what caliber you are loading. Once you add the casefeeder to the RL550 you are limited to loading pistol calibers. The only exception to this would be 223 and 300 AAC. With the proper adapters these are possible to load as well.
