No matter what I do with this gun, It fails to feed.

I'm a max load on for the .380 on an FMj, and it fails to feed, but only on the beretta.

Sig, Glock, any other .380, no problems.

Any ideas aside from bad magazine and Ejector rod?

Have you adjusted the overall length, in or out?

Make sure it isn't designed for a specific cartridge.

Does it fail with factory or just handloads?

Its very strange. It fails with just my handload. Factory it works, other handloads it works, and specific handload in question works in 2 other .380s, just not the baretta.

If it is a new gun you might try shooting it a leased 50 times then see how it feeds in general, I have seen many new guns that need this to straighten out feed issues. Craig

It sounds more like the OAL issue, maybe...If you are shooting a factory, or "other handload", round with a similar nose profile how do the OALs compare?

thanks, I've put several hundred rounds through it. So that's not it. I am using the OAL listed in the manual. I'll check it against an OAL for factory round and see if I"m off.

this beretta sure is finicky.

Any time there is a fit problem with handloads, measure.
Measure the OD of your reloads i a few places, measure
the bullet diameter of the bullet, and double check the
OAL of your rounds (can you do a plunk test with your
gun?). Are the rounds entering the chamber at all? Rounds
get stuck at the mouth of the chamber? What type of
failure to feed are you experiencing?

The FTF's always slide lock back. Only reason I am ruling out magazine is that it keeps happening with several different mags. Does not happen with fac rounds.

Okay, measurements are spot on.

Could a crimp issue cause a slide to lock back? I can't see how, but am i missing something?

Again, all measurements spot on, Powder charge at the top end for a .380 auto firing FMJ's using tightgroup.

Does it stop on the same round every time or is it random on which one
it locks back?

Unless you are using the same bullet as what is listed in your loading
manual the OAL can vary as ogive shapes vary from bullet
manufacturers even with the same style of bullet.

I have 2 different casters 124gn cast rn bullets...one seats at 1.145 the
other goes all the way down to 1.090, difficult for the naked eye to see
some differences but the gun sure notices

Different bullets, different brass, different primers, only powder has stayed the same.

Does it lock back on the same round every time?

What does the top round look like in the mag any patterns?

It can be hard to do but take a deep breath and assess the situation
before putting a new round in the chamber, dropping the mag or any
other attempt to get back to shooting.

How is your grip on the gun, is your thumb near the slide lock?

"Lock back"? Perhaps the loads are too hot, slamming the
slide back hard enough to "lock" it back? Does the slide
lock engage?

There's no more frustrating situation in hand loading than to have a pistol that feeds factory rounds, but not one's own hand loads, even when said hand loads work in other pistols.

This is one situation in which specifics tell us much & pictures are our friends. Can you tell us what the handload consists of, in terms of charge weight/ propellant/projectile weight & configuration + overall length? Additionally, an image of the non-feeding (sometimes feeding?) reload would help.

Also, does the pistol misbehave when other shooters fire it? I MIGHT be a case of some part of your hand brushing against a slide release or safety in just the right way for it to cause FTFs.
You do not mention which model of Beretta .380 you are using,and this could be significant. If it is one of the old M1934 models, the cause(s) of the problem(s) could be much different than those for one of the more modern designs. The older models tend not to like jacketed hollow points with "squared off"(like a truncated cone) points, but will feed FMJ or LRN bullets all day long.

Lastly, I'm QUITE sure that you clean and maintain your firearms, magazines and reloading equipment, and other items as well or better than many of us on this site. BUT, I also recommend that you field strip the pistol and search for rough spots along any surfaces that contact each other, or the cartridge & smooth them out accordingly. Also look for gunked-up extractor claws and battered or peened ejectors.
Doing a similar thing with the magazines may also reveal troublesome spots which can be honed away.
I doubt that even very dirty reloading equipment, if it turns out reasonably clean ammo, is the culprit, but you may as well be thorough. Pull apart the seating/crimping die, especially. Clean it with gun cleaner, dry, oil, and assemble.

LASTLY, it MAY just be a matter of altering the cartridge overall length a small amount, to make it work in this particular pistol. I've gone from miserable to flawless reliability in some pistols by shortening or lengthening the round for it, by 0.002"
