Hello, new to this Forum. Long time Dillon user. I have a 458 socom upper on the way and now I'm looking to reload for it. Is there such thing as Dillon dies for this caliber? and which shell plate do I need? I currently load .40, .44 and .45.

.458 Socom uses the same shellplate as 45ACP. It does require a custom funnel , #21440 . Dillon Precision has no intention to manufacture dies for this cartridge, due to very low demand.
