I placed my order Jan 19, 2013 knowing full well the state of affairs would be getting worse if I waited any longer. My 550 showed up about 3 weeks later. Not too bad considering I was ready to wait 4-6 weeks. However upon inspection I noticed the 45 ACP die set I order was not present. I sent an email noting my situation. Didnt hear back so I purchased "from another source" a 10/40 die set and caliber conversion figuring it would show up soon enough. With those 10/40 parts in hand I decided I would assemble my machine now. After laying the parts out I now see I am missing the 45 ACP caliber conversion kit as well that my machine should have came with too. Are these components being shipped separately due to the back log? Im confused and havent had any response from Dillon regarding my original concern regarding the die set not being shipped. Now I realize I dont have the caliber conversion kit either. Im gonna send another email but I have no idea if they even received the first email I sent. How should I proceed? Any thoughts or ideas would be appreciated. Any similar experiences? I'd love to hear about it?!
