I'm loading 9mm and 45 acp on my Dillon 650, never had any problems until lately I've been getting proud primers. Mostly on 9mm
but it's starting to show on the 45 acp. Bought the machine new, it's round count sits somewhere between 40,000. and 45,000.
Before I call Dillon, does anyone have a quick fix for adjustment? I'm using Ginex primers, and have used them successfully for 3 or 4 thousand rounds, when I ran out of CCI.
thanks....
Dave.
 
It's probably the primers. I use Ginex as well, but they are by far the hardest to seat properly and require a lot more force than other brands. It might also be the brass, or a combination of both. S&B brass, among others, have tight pockets, couple this with the primers and you get the problem your describing. I put everything on a table, find the wobblers, get them back on the press and reseat them flush.

If the above isn't your problem, I would check/disassemble/clean the primer punch assembly (part# 21380/21381). When reinstalling the primer punch assembly, make sure it's tight and that it protrudes through the shellplate enough to seat the primer properly. Also, check the punch support bracket (part #13488) to make sure it's in good shape.
 
Make sure the primer dealie is screwed all the way in to the bottom of the shell plate assembly. They back off occasionally.

Other than that... Ginex primers are a little on the big side, they seat a little hard sometimes. Especially in brass with tight primer pockets like S&B. Gotta give them an extra bump on the handle to get them seated sometimes.

Thanks for all the replies. I'll take the primer punch apart & clean it, I know its screwed in all the way---check it every time I change primer size. I'm not an S&B snob; but I try to throw away S&B cases, but obviously some do slip through. LOL.
I don't shoot competitively any more, so I have a tendency to shoot cases til they fail. I wonder if the cases are so worn the pockets are loose? Does any one know if Blacksheep brass is still in business?
 
How are you cleaning the primer pockets before loading? The "load the brass till it fails" comment got me wondering if they are just full of carbon.

I have zero issues seating ginex sub flush on all of my mixed head stamp 9mm brass. But I also use a different press. I suppose I'm trying to say the primers and type of brass aren't the problem.
 
FarmerDanz, I'm wet tumbling with a Frankfort Armoury rotary tumbler.
Load the brass till it fails refers to splits and cracks in the body of the case.
Gave up trying to keep track of how many times cases have been loaded; 30---40 times or more probably, which makes me think the primer pockets are loose. Dillon says there is no adjustment concerning primer seating depth on this machine. I've added a few layers of cut up soda can and placed them under the primer punch. I'm back to a couple thousands of an inch deep, now.
Just have to come up with a little better way to make this fix more permanent. Thanks for all the input, guys!
 
FYI, found some Blacksheep camdex processed 9mm brass at double tap sports, one of our sponsors!
Good price........ordered 1000.
 
Just ONE more suggestion…had a similar problem arise seating primers proud with one of my 550 Dillons. Tried all the other tricks to compensate and FINALLY tracked the problem to shell plate not secure and as the primer would seat it would ‘float’ the plate and case UP a couple of thou. Needless to say the primer never got seated properly just below flush. Had to loosen the set screw that holds the bolt that holds down the shell plate and then tighten the bolt slightly with the large Allen key that came with the machine. Then re-tighten the set screw so it doesn’t come loose. Your 650 is the same as a 550 with a few more bells and whistles. My machines are high mileage also. Hope this advice helps, better late than never.
 
The easiest way to set the center bolt tension on those machines is to tighten it down until the shell plate stops rotating, not allowing the ring indexer to rotate and the platform to lower itself when the ringer indexer makes contact with the indexer block (do not force it). Slowly loosen the bolt until the shell plate just starts to move, and the platform is allowed to lower itself completely (hold the handle so that the platform doesn't come crashing down). Perform some test strokes to make sure the shell plate is moving freely and that all the positions align perfectly.

Despite all these tips, the seating problems are probably still related to the Ginex primers. I've loaded them all and Ginex is by far the hardest to seat fully/properly. Switching from Ginex to Federal, CCI, Winchester, etc. mid-reloading makes the difference in seating resistance very noticeable. This is not a knock on the performance of Ginex primers. I've used thousands, and they've all gone bang as long as they're seated properly.
