I've been running my Load Master for about six months now, trouble free for the most part after working out the initial bugs. 9's, .45 and .223 have been ran, using a universal decapping die in station 1 and the un-pinned sizing die station in 2. A couple weeks ago ago I loaded 600 9mm with no hiccups whatsoever. Other than emptying the powder nothing has been touched on it since then.
Sunday I decided to run some 9mm rounds. Loaded the powder and adjusted it, then started running. First half dozen or so were fine. Then I got a crushed primer. next one was crushed too. Then I noticed the primer wasn't punched out. Checked the decapping pin and it was bent. Replaced it, and then started getting flipped primers. Then I was crushing cases in the flare/powder die. Long story short, I had just about every issue possible come up - timing, indexing, primers, powder, angled bullets, jams, smiley faced primers, case feeder and so on. I bent not one, not two, but three decapping pins! After an hour and a half I just had to walk away from it.
I came back a couple hours later and completely stripped the whole thing down. Cleaned it, lubed it, reassembled and adjusted everything. Now it runs like a top again! Well, it will once my replacement pins get here later this week. It just baffles me how it could go from working perfectly to a complete nightmare with nothing being touched or changed. Ah, the joys of the Load Master!
