dagger10k Posted July 23, 2010 Share Posted July 23, 2010 I just got a new 550b (loading in 40 s&w). I have loaded maybe 10 rounds or so, but the primers seemed to not even be seated flush on them. I decided that the little plunger that seats the primers in the primer bar must be too far down, so I loosened the set screw, and raised it slightly. At this point, I can't get it to work at all. I'm having every kind of problem. Getting the brass primer holder thing to actually line up with the bottom of the primer magazine is proving just about impossible. Sometimes it bumps against the side of the housing, so it won't go in; sometimes the blue feed lips of the magazine are just a hair too low, and end up stopping it from going in all the way; sometimes the primer plunger doesn't go into the shell plate correctly. No matter what I do, solving one problem seems to start another. I followed the instructions in the Dillon manual to put it together, and it seemed to work ok then, aside from the underseating of the primers, but for the life of me I cannot get it back into a working configuration. Are there any instructions on how to do this? I looked at youtube, and searched here, but haven't found anything addressing this exact problem. I've been working on this for the last couple of hours, have spilled hundreds of primers on the floor and everywhere else, and I think if I keep trying to do this myself, I'm going to break something, assuming I haven't already done so. Any help would be very appreciated. Thanks. Link to comment Share on other sites More sharing options...
