New to reloading and I am going to set a press up to reload .223. Have a Dillon 550 and everything I need to start. Kind of unsure how to set the dies. Manual isnt real explanatory. Any help would be appreciated. Cant wait to get started. And if anyone has a Dillon 550 I am a machinist been thinking about machining some billet aluminum die blocks and some 4140 steel or stainless steel powder dies. Just wanting to see if there was any interest in these first before machining a bunch of them.
