After reloading for 27 years this has never happened to me before. I am loading on a Hornady AP LnL. The hopper on the powder measure fell off. I looked it over real well and the best I could tell it was just a press fit. I pressed it back on as best as I could. I even put a block of wood on top and tapped it few times with a hammer to make sure it was in real good. In just a few minutes it came off again. Do they use a special kind of glue to hold it on? I tried to call Hornady, but just my luck, they had closed 5 minutes earlier. What do I do. I was planning on doing some reloading this weekend.
