Got a dillon 550 in july, and my round count is 10k on it. All 9mm. Every 1000 rounds i clean it up good and re-oil.
Tonight i have had my worst failure rate ever. It coincides with starting a fresh new batch of brass.
I was wondering if these faillures happen often to you? Tonight i must of been in the 15% failure it was awfully long reloading.

Left picture primer stuck halfway in, center decapped primer and did not insert a new one when i felt resistance (one of the rare ones as i usually pushed one halfway in) we see the rim of the old primer and center just got out, right the rim of the casing crushed on station #2 (flaring and powder) brass was perfectly round at start.

 
Right side-the mouth, not rim of case has been crushed. Some brass has the inside of mouth very sharp or burred, and will benefit from inside mouth chamfering. Your flaring tool may need to be removed and polished(fine steel wool or fine emery paper), to remove roughness or a coating of brass metal. Check to see if your primer pockets are too small(brand=s&b?) or primers are too large . good luck
 
rshew, The fixed plate on the shaft has never been removed. I have heard if ever i do this it needs reindexing afterwards with a special tool. The rotating shellplate has been tightened a bit. It helped to some extent with the crushed casings, but still got some. I had slacked it a bit so the click stay's smooth to prevent powder spillage from station 2 to 3.

glycerin, i will remove flaring tool and very slightly dremel it with the white buffer tip. I will go very slowly, i'll let you know results once it's done.
Primer mystery has been solved, brass issue. My new single fired brass lot, has mixed headstamps. And every single FC ones, the primer breaks instead of removing on station 1. And with the rim of the old primer in, the new one won'T come in. I have had about 50-60 so far like this, 100% FC no other brand did it. It's a shame as once shot FC is usually my match brass, as i personnaly find that they end up with the most consistent OAL.
 
the primer not seating properly might be crimped primer pockets, they for some reason feel the need to crimp them...
 
First time i get this, and my round count is in the 10k on this press, and 50% of it was FC because it's all i shot when i was shooting factory. This is a once fired scrapyard brass not my own.
 
are the primers sealed into the primer pockets on the federal brass. i know the federal 222 rifle brass has a blue or red sealer around the primer as well as a crimp.
 
some FC brass is crimped, some is not. you need to check each one, I know it sucks.
Unless you have a dillon super swage, just toss the crimped 9mm in the brass bin...
10% of my 9mm 1f brass was crimped, all FC.

the crimped brass have a ring stamped around the primer.
 
I may be wrong but I believe that you did not fully cycled the press as I have seen this before from others who have had the same. Push/pull your handle to the end of the stroke.
 
I have had the same issues. Its range brass? I keep a bucket beside the bench and just toss the ones that get a stuck primer. You may get a bunch of crap brass once in a while.
Also, make sure that you do full strokes of the handle so that the next primer gets picked up, short stroking can cause it to not go far enough back to get a primer out of the tube.
 
If you got berdan case in station 1 and a boxer case in station 2 it might be very hard to seat a primer

you also might have ended up with a extra long seated round

always got problems with federal brass marked '''NP''' on my 650XL. i simply ditch them on sight. other than that and S&B very tight primer pockets, not an issue.
 
I am confirming, it's an FC brass issue. All of these doing this are FC. My personnal once shot FC don't do it, but this scrapyard FC brass batch is junk. Their nickel plated WIN on the other hand is very nice and shiny, practicly glides thru the 550. Thanks all for chiming in, my equipment was ok afterall. I even had changed the decapping pin lately just to be sure.
 
Decap all crimped fc brass in the lee decapper, then lube, then fl resize with lee die, then tumble, then remove milcrimp with dillon super swage, then its as good as the rest of your brass. Use lee fcd laststep Or, brass bucket and dont use it.
