is where this thread is headed. I load all my pistol ammo on a Dillon 550. My next adventure is to try and load large quantities of 55 gr fmj 223, probably using Montana Gold for my AR's. Probably going to buy another powder dispensing unit, dies, and tool head. Question is: has anyone loaded large quantities of this caliber and do you have a specific method for doing so? It's too bad the technology isn't there for a carbide die that would work on a necked case. Thanks in advance for you input.
