Doing that.

The bullet bulge is causing the binding.

Yes, and I'm not seeing any pieces on the shell plate.

It might make it hard to eject rounds.
The bullet jams in the lands in my CZ. While most people wouldn't notice, when I'm shooting a USPSA match, I may be done with a stage and have to unload. I've had bullets stuck in the chamber after I cleared the CZ and the Ruger PC9.

Jim,

The problem is probably the inconsistency of the PC on the bullets. I make my own PC bullets and I size them through a Lee push through die. If I don't do this, some bullets will bulge the case, even though they go through a Lee Factory Crimp die on the Dillon 550. This will cause problems in my S&W M&P and my Kahr P9 as the chambers are both tight.

I suggest you get a Lee .356 size die and size them before loading or switch to another brand that might be more consistent.

If it fits in the gauge, it's fine for all three. If it's meh, it jams in the CZ and STI. If it's"I need a hammer" I just take it apart and start over. But it's really annoying loading up 500 rounds and and finding 50 need extra attention or dismemberment.
Huh?

It sounds like you are loading the rounds long then. Increasing the crimp should not affect the bullet touching the lands.

Now, too much crimping can bulge the case, causing issues.

9mm headspaces on the case mouth. If I crimp too much the cartridge will go in too far.

I like John's suggestion. It doesn't hurt to run the PC'd bullets through a sizer before you load them. Lee makes a .356 kit that you can get for ~$25.

I did look at the brass for brands and they're all different.

And you'd think they'd resize after coating the bullets . I'm trying to get around 1000 rounds a week but this is killing my speed. After dinking around with the bad rounds, it's taking an hour per 100. The only reason I'm sticking with these bullets is I'm using less powder per round of Titegroup. I may have to go with another bullet maker, just hoping there was an easy fix.

But it should not jam the round into the rifling. There is nothing pushing it in that far.

And the extractor should prevent it from going that far also.

And finally, 9mm is actually a tapered case, not truly straight walled.

That said, you should only crimp enough to remove the flair.

I finally broke down and bought a separate 9mm resizing die and got it yesterday. I pulled the decapping pin assembly and ran the oversized ammunition through the resizing die. Now they fit the case gauge. Testing some today.

I do that when reloading 7mm TCU and 223/5.56....just a little bump. Also had to do it with 45 ACP when I got a batch of .452” bullets. Normal cast bullet diameter but I found out the bullet maker had mixed them up with .454” bullets. I used the Lee FCD die to size them down until the bullet sizer I order arrived.
