FireNHole Posted August 30, 2014 Share Posted August 30, 2014 Hey guys. I've had my 550 I purchased through enos now for a couple of months. For the first couple of thousand rounds I have been using my already federal match primed 9mm cases. These were pulled due to a bad load. Long story. So a few days ago I re-insert the decap pin and start loading up. Very soon there after I noticed a common occurrence. I am talking like 20% of the time I am either getting no primer in the primer cup or the primer is upside down when in the cup. I read up online. Watched some videos. I thought it was the thin bar that goes from the primer tube down through the 2 wheel tracks. I ever so slightly bent it so that it would apply more force on the bar to make sure it was going back all the way. Things got a little better after that. However I am still having the problem quite frequently. I could expect this like once every couple hundred of rounds but not 10 or 20 out of 100. It seems to work perfectly if there is no brass in station 1 ( only did this for testing purposes ). When brass is in station one it seems like the force of the case being resized and decapped is causing the primer cup to be little higher which is causing it to run into the primer that is getting ready to drop. I have taken the bar of multiple times and made sure that the primer cup was compressed as low as it could go. I am not sure what else to do. Any advice would be grateful. Thanks!

james5m Posted August 30, 2014 Share Posted August 30, 2014 First take the operating rod(13869) & primer slide return spring(13928) off and move the primer slide in and out and see if it move smoothy in the housing. If you have overtighten the screws it will cause the housing to bulge and bind the slide. Check and see if the primer cup and punch has a installed height between 1.215 - 1.220 HTH Jim 9 Link to comment Share on other sites More sharing options...
FireNHole Posted August 30, 2014 Author Share Posted August 30, 2014 Thanks for the info Jim. Checking that stuff out now. First take the operating rod(13869) & primer slide return spring(13928) off and move the primer slide in and out and see if it move smoothy in the housing. If you have overtighten the screws it will cause the housing to bulge and bind the slide.

FireNHole Posted August 30, 2014 Author Share Posted August 30, 2014 Took off those parts. The primer slide goes back and forth smoothly with no problem. I checked the height of the primer cup and slide and its 1.217. Is it possible the primer assembly inside the tube is too low? Here is a pic.

GrumpyOne Posted August 30, 2014 Share Posted August 30, 2014 Several things to check. Check make sure you have the correct tube in the primer feeder, check to make sure that the primer feed tube is "clicked" into position. From the pic, I'll bet you have the large tube in the press and it's not clicked in. Unscrew the top nut, remove the primer feed tube, put the correct one in, turn slightly till you feel it seat, put nut back on top of primer tube assembly.

I assumed it was small primer tube since I ordered it for 9mm conversion and only bought 9mm dies. The small primer cup was already installed as well.

open17 Posted August 31, 2014 Share Posted August 31, 2014 (edited) Goofy as it sounds, the nut on top may be too tight. Talking about the knurled nut at the top--the part that retains the inner primer tube and has the low primer warning unit clamped to it (if so equipped). I run mine just barely snug and primers feed fine. Too tight and it won't feed. Yes--I've replaced and adjusted everything else! ETA--Grumpy may have hit it, you have the wrong tube in there. The tip on a small primer tube is BLUE. I'm seeing a red tip in the pictures. Edited August 31, 2014 by open17 Link to comment Share on other sites More sharing options...
FireNHole Posted August 31, 2014 Author Share Posted August 31, 2014 Thank you all for the help! It was the wrong tube! Feeding is consistent now. I really appreciate the comments guys! Link to comment Share on other sites More sharing options...

CSStreett Posted August 31, 2014 Share Posted August 31, 2014 I've always wondered why Dillon ships the 550 with a large primer tube and the small prime bar installed. Link to comment Share on other sites More sharing options...
