primers fall thru magazine

Setting up a new 550B for 9mm Luger. I have everything adjusted per instructions. I am using CCI small pistol primers. Changed 550b to small primer seating cup and put small primer magazine in primer tube. When I dropped the primers from the pick-up tube to the magazine tube they fell out of the bottom. I can feel the notch on the magazine tip is seated.

When the seating cup moves to the cartridge, primers continue to fall out of the magazine.

Please help, seems like something simple I am overlooking, but I cant figure it out.

Thanks

RE: primers fall thru magazine

It sounds like the alignment ridge on the magazine tip is not lined up with the corresponding groove. Because of this, the tube is not bottomed out in the housing. Rotate the magazine tube until the ridge lines up, then the entire tube will drop down about 1/4" more.

Thanks, there must have been a burr on the tip of the magazine, had to push very hard to get it to drop down, but it works now.

Pushing 'very hard' sounds like it was not lined up correctly.  Check that it is lined up with the corresponding groove. :)

RE: primers fall thru magazine

  I have had my RL550B for 25+years now and have had that same problem with mine in the past.  The primer tube(s) were seated correctly and with some investigation I discovered that the lips on the tip had relaxed allowing the primers to drop right through.  I found that by rolling the 2 flexable pieces at the split, first one then the other inside the other it reshaped them to work again.  I have had the same problem on both small and large primers and used the same cure on both with the same success.

RE: primers fall thru magazine

This is an old thread, but there's something to add that may help someone.
I had the same problem. I had the correct magazine tube inserted (small rifle in my case), and the tongue and groove on the end were oriented correctly as evidenced by the tube seating further when lined up correctly.
However, the problem persisted. The primers kept on falling out of the end of the magazine until it was empty. They tended to scatter, though most of them stayed on the primer slide making the clean-up annoying but not terribly time consuming.

In desperation, I pulled the magazine tube yet again and reinserted, this time with some twisting and downward pressure. I discovered that after the first time it dropped, if I continued to push lightly while twisting slowly back and forth, it would drop a second time. The first drop was easily achieved. The second small drop required some persistence, slight pressure, and moving the circular orientation slightly. After that second drop, it worked as described in the manual, but, gee, it was difficult to figure out -- easy to do but difficult and time-consuming to troubleshoot and finally figure out.

Dillon really should either re-engineer this mechanism or post videos and add further explanation in the manual and DVD about troubleshooting primer-feeding problems.

RE: primers fall thru magazine

Hi, I have the same problem of primers falling through the primer tube, I have tried a brand new tip to the tube the primers still fall through the tip even when not in the machine, so you can not remove the tube without spilling the primers ( I am trying to change the tube from small pistol primers to small rifle primers ).
Regards,
Kevin Hosey.

RE: primers fall thru magazine

Kevin, the tips are not meant to hold the primers in the tube. They are meant to align the primers with the primer slide. The primers are held in the tube by the primer feed stop pin #14051. It is in the housing at the bottom of the primer tower with a tension spring on the back. If that is sticking back then the primers will fall straight through the tip. Check and make sure that the primer stop pin slides in and out and doesn't stick, may need cleaning. As to removing primers from the tube to change them, you need to remove the whole primer tower and pour them out the top to keep them from falling out the bottom of the tube when you lift it out. I try and load in 100 round increments so I don't have to remove any primers from the tube in the tower. If I am doing odd lots I will only load enough primers for the rounds I am doing.

RE: primers fall thru magazine

New poster, I had the same problem recently after a cleaning and it was due to a buggered up flexible orifice (part number 14024). In my case I had dropped the primer magazine a couple of times while installing it in the primer housing. The bottom of the tab mushroomed a bit and prevented it from seating in the groove in the primer housing shield. I cleaned up the tab with an exacto knife so I could easily feel when the tab and groove are lined up now. Then I made a couple of reference marks at the top of my magazine tubes to indicate the tab location and a reference line to indicate when the tube is fully seated. Playing find the primer isn't a game I want to play again.
