9mm reloading help needed

[calebp]

Hey Guys,

Been reloading 9mm for a while now. Have a load for suppressor use that has never really changed but am having issues in a specific gun. Reloads feed flawlessly in my P226, factory threaded g19 barrels, ATI threaded G43 barrel, and an MPX without issue. Recently dropped a threaded Faxon match barrel in my new g19 and am having FTE/double feeds in ammo that runs flawlessly in all other guns I have shot it out of. Assuming the chamber of the Faxon barrel is a little tighter and it's not quite ripping the rounds out and the next round is feeding on top of it. I've not really set my Lee to crimp much at all because I've always heard you don't really need to crimp 9mm. Should I crimp a little more or is my expanding die just over expanding the case mouth?

Thanks!
Caleb

9mm is a tapered round. Are you using a Lee taper crimp die?

Does the barrel work with other ammo?

It could be the barrel, or the ammo.

I would try some cheap fmj factory ammo and trouble shoot.

Your barrel may have too much lock up or too tight a chamber. Glocks and Sigs have very generous chambers—.

Functions flawlessly with factory 158gr ammo with the can attached. My G43 with ATI barrel and can also cycles the reloads flawlessly.

TBH not totally sure, its the 9mm die set that came with the Lee Pro 1000 and have never had issues of any sort running the same ammo in any other gun.

If you have a phone with slow motion recording. Record a few failures and post them. It should be clear what type of failure you are experiencing. If it is always the same type of failure describe the position of the slide, fired round and unfired round. There are many separate processes happing in a short period of time when firing and reloading a round.

I load with the same set up and roughly the same oal. I'm interested in what you find out.

Have u taken the barrel out of the gun and verified that the loaded ammo will drop freely and fully into the chamber.

If it does not drop in, you will need to tighten your crimp die and/or seat the bullet deeper into the case. Or, get your new barrel’s chamber reamed.
