Dealing with crimped primer pockets on 223 brass

I am looking for suggestions as to dealing with 223 brass with crimped primer pockets, i cannot always tell which brass is crimped and which isn't until I try to prime it, this typically smashes the primer and slows things down. The only thing I can think of to fix this is to resize and deprime all my brass on my single stage, then sort the brass and run the crimped brass through the primer pocket deswage press, then load it back into my hopper. Obviously a big waste of time. And I have 3 5gal buckets of 223 brass

RE: Dealing with crimped primer pockets on 223 brass

I load 9mm but deal with crimped primers as follows.
I prewash the cases for about 15 minutes to remove the range crud. Then deprime only with a de-prime Die such as a Lee universal die, it goes very fast.
Then wet tumble the cases and when dry use a go no go primer check gauge https://ballistictools.com/store/swage-gage-small-primer-pocket
I load about 1200 rounds a month.
The only alternative is to by a CP2000 or rl1100 and swage every case.
I am happy with the 750 so it is a cost effective alternative to spending another $2,000.

RE: Dealing with crimped primer pockets on 223 brass

I have 2 550's but I have processed a lot of 223 brass for myself and friends. I tumble all the brass to clean off the crud and then a quick inspection for cracks and crimps. Anything I am not sure on the crimp goes into the crimp box. I run all the brass through a 550 set up with a size and de-prime on station 1 and a rapid trim 1200 on station 3. The uncrimped brass would go into the ready to load bucket and I would run the crimped brass through my super swage. It takes time but then the brass is ready to load when ever I am ready. I process the brass when I get half a bucket or so to keep from have a lot of unprocessed brass to do at one time.

I use Swage-It when make first round (deprime and Swage) on 5.56.
I use Lee Universal decapping die.

RE: Dealing with crimped primer pockets on 223 brass

Have/had the same issue. Using the Dillon super sewage was an all day thing trying to process 223 military brass. My solution is a bit expensive. I have a 750, located a new 650 that was set up for 9mm. It was 650 out the door. Bc of the shortage of 9mm ammo the conv kits that sell for 85 bucks, sold on eBay for 290. Got 1/2 back. Ordered a trim tool head 45, a power supply for the Dillon case feeder and a case trim system for about 325. Added a sewage it swagger for 130. This tool attaches to the 650. Will not work on the 750. I set the 650 up as a dedicated case processor. I use the case feeder from the 750. I can process military brass as fast as I can pull the handle. Total out of pocket is about 8 bills. Give me your email I will send you pic of my set up and all the related purchases.

It should be noted that the Swage-It voids your Dillon machine's warranty. My brother actually bought one but didn't use it when he found this out. Apparently it can apply excessive force to the machine. Essentially, it installs in place of the primer punch and pushes *hard* against the shellplate, much harder than the priming force. I actually think it would be okay if a die was countering the upward force, and I have seen such dies for sale, but not specifically for this application. The die presses downward on the *inside* of the case. Since cases can vary in dimensions, therein lies the quandary. Perhaps the downward force could be spring loaded.

RE: Dealing with crimped primer pockets on 223 brass

If the use of any on-press swaging tool is considered an "unauthorized modification" to the press, that seems to me like important information that should be included as a cautionary note in the manual. It wasn't in the XL 650 manual and it's still not in the XL 750 manual. I noticed that the Swage-It seems to operate on the "priming stroke" and without a backup die, where the forces on the press are not generally high. Dillon does offer on-press swaging on the '1050 and '1100 machines and I wonder if they have considered the possibility of designing a system compatible with the lesser machines. Now that the priming system is different on the '750, it might be more feasible to create a retractable system that operates with a backup die.

RE: Dealing with crimped primer pockets on 223 brass

The 1050 and 1100 work in a different way (the die head moves down onto the shell plate), and the swaging system is designed to work with a supporting die and does not put upward force on the shell plate. If you find a video of that system in operation and compare it to how the 550/650/750 operates, you'll see that there is really no way to design a swage system that does not put upward pressure on the shell plate - which Dillon says it is not meant to do.

Of course it would need a backing die, but that would only preclude the powder drop from occurring at the same time. De-prime, de-swage, and trim. It would take two rides on this merry-go-round.

I am also dealing with a fair amount of crimped 223. My plan is to just get the Lee APP and set it up to swage. For the price, I don't care if I ever use it again after I process the brass I already own.

RE: Dealing with crimped primer pockets on 223 brass

I have a Lee rotary that I use as a single station.
After 30 minutes wet with SS pins I dry and lube, then punch the primers and move over to the Super Swage.
Don't even bother looking at the head stamps.
Then light pocket ream and brush then size, next it's into a sonic tank for a few minutes, dry re-lube and then over to the 750.
Yes it's a pain. Takes case prep to a whole new level.
