I have a Dillon 550 that I’ve used for about 2 years. I’ve had a Lee turret press that I used for about 15 years. I like the Dillon but I’m have trouble with primers seating. I get about 10 to 15 primers per 100 that go in sideways. I can feel the difference as they go in. By the time I feel the difference it is too late so I have to re-size the case to get it out. Most will be fine with the next primer. I’ve cleaned the primer seating pin after it happens but that does not seem to matter. I also get about 4 to 6 per 500 that the primers flip and seat up side down. I can’t fell this and find it when I try to load the ammo in the mag. For now I’m only doing 9mm on the Dillon.
Has anyone seen this before and is there a fix? Thanks Ken |

It can happen with small primers in a small primer tube. Not often, but it does happen.
Make sure your primter pick-up tubes and primer feed tubes are kept clean. While I'm not familiar with the primer feed system on a 550 (I have a SDB) I'm sure that they're fairly similar. It might be that the "timng" is off a little bit....that the shellplate is a little bit off causing the primer in the primer cup to catch on the side of the hole and be inserted sideways or upside down. You'll definitely hear a "SNAP" when this happens. The SDB has an ajustment screw to advance or retard the shellplate. Might want to see if you press has the same. |

I had a buddy that just went through the same type of problems and I couldn't figure it out until we tried to replace the feed tip on the "inside tube" and realized it was the large tube and should have been the small one!

Dillons priming system sucks balls. Here's what I've gone to:
I remove the operating rod from the auto priming system and simply CYCLE THE FEEDER BY HAND!! By manually cycling that crappy system, you can eliminate the jerky/sticky hickups and ensure the primers no longer flip in the cup. I haven't smashed a sideways primer in years and no longer ever get upside-down seated primers. I don't mind manually running the system because it beats the shit out of the aggrivation of clearing the machine when you mash a primer. |

This is just wrong. The Dillon priming system works just this side of perfectly. All machinery needs to be cleaned from time-to-time. Especially when you have primer residue falling onto the bearings. If you are getting primers sideways, you have a problem with your set up. Check to make sure you have the proper equipment installed (small tubes, small feed tips, small feeder bar,...). Then, just clean and lube the primer feed system. I use a prodcut Dillon sells called "Snake Oil". It is a low viscosity oil like a mineral oil. One drop beneath the primer feed bar and the steel base plate and I have zero feed problems. |

Maybe you should also consider calling Dillon Tech Support too. I ran my 550B over 70,000 rds before I sold it and have run my XL650 over 30,000 rds. While I get the occasional primer problem, it's been very rare. I keep my press clean, adjusted, and lubed and have had no issues with the 550B's priming system at all after I replaced that damn thin cotter pin they give you to hold the Spent Primer Catching Chute with a finishing nail. My XL650's priming system has run smooth as glass right out of the box, however, adjusting the Station #2 Locator Tab to center the case so that the primer feeds cleanly is an 'acquired art.' |

Especially when you have primer residue falling onto the bearings. I clean that turd all the time! I don't mind manually feeding primers. I know I could drive down there and they'd make it wonderful again. But I'm fine stuck in my old grumpy ways. I like slowing the loading process a little to ensure absolute quality. |
| You have to get the travel adjustment screw set exactly right. This is the thing that controls the centering of the primers in the priming station. A least it is that way on my 450. Its not so bad for me with the large primers but on the small primer setup I spend a great deal of time to make sure that the primer cup thing is centered exactly in the middle then the primer arm is extended. I also find it helps to keep the primer bar really clean so that it slides consistently. Also you don't want to have the primer tube screwed down to tight, just a little. |

I checked my Primer slide and I was using the small one with the bronze seating cup. I'm also using the small primer magazine with the blue end. I cleaned everything today and changed to a new bronze seating cup. If this doesn't work, I'll give Dillon a call.
Thanks everyone, Ken |

Thanks everyone, Ken If it won't work with it centered exactally try it a little to much forward and then a little short of center. Once you get the right spot it will be OK. |

Not just primer residue but also powder will fall in . I keep a air hose next to the presses and blow them off from time to time as crap builds up. |

Quoted: On a side note my primer bar would get stuck cycling sometime, after close inspection the bar is roughly machined, a quick sanding and polishing to a mirrior of the wear areas have made it 100% perfect. Most likely it wasn't machining but a sign that it's time to clean the slide and bearing surface. I also noticed after about 35,000 rds that I developed a slight galling of the underside of the slide and the bearing surface. I found that if I cleaned them well with brake fluid and then polished both the slide underside and the flat bearing surface with my Dremel and buffing compound, that the issue would disappear. |

Smooth is the word for Dillon. When the primer bar on the 550 returns, it needs to return smoothly. I remember I First used a Dillon CLANG, CLANG, CLANG - Opps a sideways primer. I learnd many years ago that SMOOTH is the solution. When the primer bar returns under the shell plate it should just stop, not ram.
I can flip primers on my 650 with not problem, because it also likes SMOOTH ! So SMOOTH is good, JERKY is BADD ! |

Primer shuttle needs to move without jerking. This means careful manipulation of the handle. Also, premature primer release can cause tipped/backwards primers. Slow down and inspect the primers as they are traveling on the shuttle. After seating a primer, release the handle, rotate the shell plate, then act like seating a primer with no shell in station 1. Wipe down the priming ram with a finger, this can collect junk like polishing media and also cause tipped primers. |

I forgot about that but I too cleaned the primer seating ram frequently with my finger when I had my 550B. |
