I'm shore you will love your Dillon 550 also , sturdy well built simple to set up and operate + the warranty . May I suggest staring slow in your loading , take your time with the setup and load small batches of ammo . When loading take the time to slowly look at each thing that has happened in all the stations every time , this could save you a lot of aggravation . A few rounds to test is easier to correct a possible issues , rather than having a thousand rounds you should disassemble for safety reasons . Besides you can play with your new toy more often .
