About 2 months ago I was loading 45 ACP with 800X and the drum started sticking in the dispense position. I tried loosening the drum so much that the powder started leaking. I had to lightly tap the charge body with a hammer to get it to release. I finally contacted Lee and they sent me a replacement dispenser body. After a couple months I went to the reloading bench to resume my efforts and after a half dozen test charges the same problem came back. Any ideas? I have reloaded several thousand rounds using of this powder in the past.
