Kind of a product/company review here. I have owned a Dillon 550B for about 12-14 years. From day one it has been set up to load for my .45ACP's. Recently it started flipping primers an putting them in upside down. I emailed Dillon and the only two things they wanted to know was age of the unit and my address so they could upgrade the unit at no cost. Dang, that's great customer service. I would /will recommend to them to anyone.
