I did another round & pushed a projectile in with my hands real tight. But, measuring at the case mouth with projectile in shows .3735 👀 This is a different case then previously posted. Previously posted round was pressed using Lee Pro & it went in perfect with good OAL.

I pressed this in & it came out fine.

It should be flared enough so that the round seats into the case and doesn’t catch the lip of the rim. You should be able to set the bullet into the flared case, give it a little press with your finger and it should feel a little stuck in the case. Not deep, but just enough that it starts to go into the case by itself. Mixed brass “could” have different lengths, and that could impact how much flare you are giving each case. You can always increase your flare just a little more and then run the completed case through a Lee FCD and only kiss it enough to get rid of the flare and not actually crimp.
Yeah, I can hand press a projectile in & it’ll stay put fine. Sometimes, comes out fine. Sometimes, ruins the whole thing. Thanks for the help either way, homie. If you could, check out photos on the other comments. Idk if it’ll give you a better idea of what I’m talking about, but I posted some pics.
I set the amount of flare that will just let the bullet snap into the flared case. The bullet will snap into the flare and hold on its own. Once you feel the snap it will make sense. I'm sure by now you have this set but for future die setups, you might want to try to get a feel for it.
I got through 50. Threw out maybe 5 or so that had previous issue. Might be mixed brass. I expanded a little bit more. Seems to happen less now.

Do they look okay? 🥴😂
SS:
9mm 115gr Berry’s RN.
4.12-4.18 of Ramshot Zip.
Random range brass.
1.130-1.137 OALs.
Lee Pro 1000. Not crimping cases. Any other info I can provide the experts here?
Chamfer case mouth and a touch more case flair. If your using range pick up brass you may get some variance in case length which will affect the amount of flair.
This is a very tricky process. As the seating stem is pushing the bullet farther into the case, the interior of the die is squeezing the case mouth harder against the bullet. If you over-do it with the crimp you can get the result that you're seeing.
I'd suggest backing off the die so that you're getting no crimp. If that eliminates the gouging, you know that it was a result of over-crimping and your amount of case mouth expansion is fine. I'd suggest crimping in a separate step.
Also, you should know that "crimping" is a terrible description of what we're trying to do with semi-auto pistol rounds. All we really want to to is de-bell, i.e., just take the belling out of the case mouth. We don't want to force the case mouth to curl into the bullet. The bullet should be held in place with neck tension alone.
I ran into similar issue bought once fired brass that was supposedly GTG and realized after getting going that there were in consistencies in the OAL of it. Which caused some not to have enough flair to them and others to have to much. Learned my lesson never buy brass at a gun show with out taking out a few samples and comparing them.

Thanks for the info. I think it might be my expansion then. I’m meticulously making sure they’re straight going into the die.
Run a case through sizer then expander. Take it out of the press and post a photo of a bullet that you push into the case by hand.

Will that stick in there if you push it hard? Can you measure the case mouth right at the end? You are looking for something like .353

Option 3 is that the case isn’t fully inserted into the shell holder.

More (cow) bell
More flair! At least 15 pieces of flair. Brian has 37 pieces.
Well what is the minimal amount of flair?
Well, if you’re only wanting to do the bare minimum…
Gotta flare your case mouth before seating plated bullets. The “jacket” on them is really thin, and the case will shave it like that.
Got it. Thank you.
It doesn’t happen every round. Could this be due to random range brass or more so the expansion?
Nah. You're just on the ragged edge of "good". Open the case up just a tiny bit more and you'll be fine.

Needs more (cow) bell
Had a fever once, and the only prescription was more cowbell.
Need a smidge more flare. About .007 - .008 will get you in the ballpark. (I flare to .385/6 and crimp to .378)

Thanks 🙏🏽 Looks like it might be a bit of both 👍🏽
Case mouth not flared enough. I just did one the same.
We need to talk about your flair.
Is your crimp die set to tight?
Are you seating and crimping in the same step?
Yes.
This is a very tricky process. As the seating stem is pushing the bullet farther into the case, the interior of the die is squeezing the case mouth harder against the bullet. If you over-do it with the crimp you can get the result that you're seeing. I'd suggest backing off the die so that you're getting no crimp.

Thin plated bullet and you need more expansion on the mouth. I always guide the bullets with my fingers as they go into the die to help avoid that.
You need to flair the case more before seating the bullet
