Crimp 9mm for Semi Auto?

[Centella]

Hi friends,
I've been reloading 9mm for about a year now with great results, and I've been shooting those handloads through a 9mm Uberti single action revolver. These rounds have never been crimped.
I recently acquired a Beretta 92FS, and I've taken it to the range a couple of times, but I've only put factory ammo through it. Before I try to reload for this pistol, is it necessary to crimp your handloads intended for a semi auto?

Thanks.

No, just straighten out the flare.
Your revolver ammo should work fine in the Beretta.

I taper crimp with my Hornady custom seating die and that works just fine. Model 19 Glocks can have problems otherwise. As PO2Hammer said
"straighten out the flare should work just fine" and that's just what a taper crimp can do.

Thank you. I don't flare my 9mm cases, I just chamfer the inner side of the mouth as others have suggested. Will try some of the revolver rounds next time I go to the range...

I no longer taper crimp my 9mm rounds and BTW I shoot several flavors of Beretta 92 as well as a 1911.

But if you do decide to crimp, it’s a taper crimp.

I never crimp 9mm. Run the expander short of the bellmouth and seat the bullet. No crimp necessary. Shot a couple thousand rounds or so through by my Canik pistol and 9mm AR. I do hit them with the deburring tool.

Of course with cast bullets bellmouthing to not shave the bullets and crimping to eliminate the bell are required.

Since I shoot cast 9mm, I do expand, then taper the mouth back in to 0.380"-0.379"
(No "crimp" per se . . . )
.

If you don't expand, you will have max neck tension and will not need to use the TC die. I only TC enough to remove what I did with the expander. Some guns with tight chambers may need to bump the mouths only with a TC.

What you have has been working, don't change a thing unless a problem shows up.

As posted, just keep doing what you're doing. Neck tension holds the bullet in
auto cases, the taper "crimp" just removes the belling, or maybe .001 more.

If it ain’t broke, don’t fix it.
You probably are loading jacketed, or maybe plated? Cast or coated are prone to shaving unless you flare enough, in that case a taper crimp will neck the brass back down to kiss the bullet.

I use a lee factory crimp die.
But the 92 didn't need it.
