Problems with jamming 9mm

[huckberry668]

I assume you haven't reloaded long from the terms you used and description. More information is needed to accurately diagnose the issue but here is a few points for you to consider if the issue isn't with the crimp, bullet seating or

1. Make sure you're sizing correctly. If you're using range mixed head-stamp cases. You may be loading 'Glocked' bulged cases. you'll end up with a bulged case too big for your chamber. The bulge will create so much fiction that it locks up your action. Just like your description. Chuck those glock bulged cases.

2. Make sure your cases are not too long. Your brass shouldn't be any longer than your chamber depth. If the case is longer than your chamber, the slide won't lock up either. However, this situation is extremely rare.

Of course first problem is loading 800 rounds without testing them .. 20 maybe, but not 800.

But...but...there's people who say staring on a Dillon is perfectly fine, you don't need to learn on a single stage or turret press first! Because learning on a Dillon allows you to load 1000 mistakes rounds an hour.

It seems your cartridges are: 1) bullets set to long in the OAL for your barrel throat, or 2) the mouth is still belled and not fitting in your chamber. As stated earlier, check your round in the barrel and adjust crimp and bullet depth from there. You may also want to check and make certain an empty case (without bullet or primer) that has been resized will fit into your chamber easily. That is really the only issues it can be without of course looking at gun related problems.

Been there done that too, what you may have is the "Glock Bulge" and I ran into the same problem. There is quite a bit of youtube info on how to correct this. About 10 out of fifty rounds would not chamber. I have a dillion 9mm chamber block is how I found out. Lee makes a die set that will size the shells loaded or unloaded, you tube is your friend

figured out the issue today. When popping he primer out the entire bullet isn't being sized correctly. Adjusted it and working flawlessly. Going to load more rounds tomorrow.

You guys are being too harsh now... Progressive is the only way to start... ESPECIALLY on a Dillon...



OP if you gots glocked brass you might still have resizing issues... But go make another 800+ rounds before you fully test that.

[Dzee16]

Not sure if you're being sarcastic there. Don't really care. Will be making A lot tomorrow.

Hey guys,

I just bought a Dillon XL650 a week ago. I set it all up and loaded 800 rounds. I'm using CCI primers, ICR target load 4.3gr powder, and a 115gr projectile. I went shooting yesterday and was getting malfunction after malfunction. One bullet go so stuck in the barrel that I needed a flat head to pry it out (not a live round). It seems that the bullets are not seating fully into the barrel because often times, the slide is just pushed back a little bit. When this happens, I can't rack the slide back and I'm forced to jam it forward, usually hitting the back of the gun on a hard surface (in a safe direction). Do you think that the crimp isn't snug enough right now? I ordered a case gauge but just wanted to get some opinions from seasoned vets.

???????

You used a flat blade screwdriver to pry a bullet out of a barrel?

I've never heard of sizing a bullet and popping primers out in the same step. Are you sure you know what you're doing? Because it sounds like you don't.

Don't shoot next to me.


I think Dzee needs to take a few steps back and start from scratch. And with some reading and learning before loading one more round.

I think he meant cartridge. Though I do have a question about his "not a live round" comment.

I've never heard of sizing a bullet and popping primers out in the same step.

This time he meant sizing a case. Decapping and resizing a case.



OP: You need to slow down a bit until you figure out what you're doing. Some suggestions:

1) Size a few cases (and I mean size only - no new primer, no powder.) Drop those into your chamber (disassemble the pistol enough to easily access the chamber) If they don't drop fully in to where they headspace on the case mouth, you are not sizing the cases correctly.

2) Take those cases, flare as normal (still no primer or powder) and seat and crimp the bullet. Take a pair of calipers and make sure your length is correct. Now drop those in your chamber and see if they headspace on the case mouth. I they don't, you need to figure out if the bullet is hitting the rifling or if the case mouth is flared and dragging on the chamber walls. You can check the former by seating deeper and retesting. You can check the latter by running a sized case through your seating/crimp die(s) without seating a bullet and redoing the chamber test.

3) If both those pass, take a look at the rounds you loaded before and check for odd bulges. Could be that your seating stem is not seating your bullets straight, causing bulges in the case body. Different seating stem would be called for.

Reloading is a process - a series of steps. Each step has to be done correctly (or at least acceptably) or the end result won't work correctly, or worse, may end up being dangerous (to your gun, your health, or the health of those who may be nearby.) Troubleshooting reloading involves verifying each step is doing what it's supposed to do.

If you don't take the time to ensure each process is correct, you are not going to get a safe and/or reliable end result.

Like the two comments above mine. I will suggest the same but stop reloading now and open a manual. Read it from front to back 5 times.

Reload 20 rounds and figure out if you have any problems.

This is the reason why a lot of us suggest single stage before progressive for new guys starting out.

Agreed. 800 rounds without checking a dummy round in a case gauge or plunking in your barrel? Seems crazy to me. Always set up your dies with a dummy cartridge, and use a case gauge or barrel to make sure they'll chamber. Then run a second dummy round all the way through the press and confirm that it case gauges. Then run 5-10 complete rounds and verify that those case gauge. Then you're set up to run a long production run.

I've reloaded tons of ammo on 650s and I wouldn't dream of not testing a few before cranking out a thousand.

"Glocked" brass is a concern in 40 and 10mm. Never had an issue with "Glocked" 9mm. It's not an issue like it is in the other calibers. Making sure your sizing die is adjusted down to the shell plate is the usual fix.

figured out the issue today. When popping he primer out the entire bullet isn't being sized correctly. Adjusted it and working flawlessly. Going to load more rounds tomorrow.

Curious whether you had read a reloading manual before you started loading? Die setup and confirming good setup is in the early chapters. Also, it's the "brass" that's being resized when you are removing the primer. It's a minor nomenclature issue, but words matter especially when discussing technical subjects like reloading.

Please read the directions and manuals carefully, and follow the directions. I get that you're excited to start reloading, but learning slowly and properly now will keep you from losing fingers later.

You also should check the terms "load development" and "ladder testing". Those terms are in most reloading manuals.

Back to basics.

Sometimes you will hear people on a rifle range say, “I’m out of bullets. Please get me some more bullets.” Usually, these people don’t know that they are asking for the wrong thing. Cartridges go into the chamber of a firearm, while bullets go out the muzzle. A bullet is only one part of a cartridge.

All cartridges—both rimfire and centerfire—have four main parts.

• Case: The case holds the primer, powder, and bullet.
• Primer: The primer compound explodes when struck by the firing pin and ignites the powder.
• Powder: The powder burns and creates gas to push the bullet through the bore and out the muzzle.
• Bullet: The bullet is the part of the cartridge that strikes the target.

Buy an undersized die, problem solved.

[TomReloaded]

I've found 9mm to be picky. Every new bullet I buy has to be rechecked and dies reset to function in my gun. They tend to run short. Way short of max saami spec.

For .40, every bullet in every weight got set to 1.135 and it always fed. Got to a point where I'd order up a totally new bullet from a new brand and bulk load them at 1.135. Always worked. I can't do that with 9mm.

I'm of the opinion that case gauges are nearly useless. It needs to plunk in your personal barrel. The barrel plunk test is more valid than a case gauge.
