I own three Dillon 550 reloaders and a Dillon 650. I load thousands of rounds and any time that something has gone wrong or broken, Dillon has sent new replacements over nite at no charge, no questions asked. Last week, my 650 had several primers detonate in the feed tube while loading. It pretty much screwed up the primer tube. When I called Dillon today and described what happened, the Tech said :"Whoa!" I am sending you a whole new primer feed system. Replace ALL the parts, do not re-use any of them. They'll go out tonight, you should have them tomorrow. These folks are absolutely awesome. I am a very happy return customer and highly recommend these fine folks to anyone wishing a quality product with people that stand behind them. Thank you, Mike Dillon.
