I have never loaded rifle ammo, but have done tons of pistol and shotgun. That said, I have an extra Dillon 55BL (https://www.dillonprecision.com/bl-550-basic-loader_8_1_25792.html) that i would like to setup for .223 since it is just laying around. I'm looking for advise on the best setup for .223 in this press. I am willing to buy the powder and primer systems to upgrade it to a 550RL and make things more automated. So for anyone that has a similar setup, what did you learn, what would you change? What else will i need? Case trimmer? Resizing die in the press or not? Be a pal and walk me through getting this thing setup the best way possible and making sure i have everything i need. Thanks in advance.
