    I have been loading .45acp lately and I got a few of these while seating the bullets....

    uploadfromtaptalk1398224748108.jpg

    I thought that maybe I wasn't getting the cases centered in the shell holder, but when I started paying extra attention to that I still got a few that did it. I noticed if I slowed down it happened a lot less but the issue was still present....are the bullets crooked on the case mouth during the stroke?

    Did I not bell my cases enough?

    The seating is noticeably stiffer when this occured.

    I am using Lee dies on an RCBS Jr press.
    Bullets are Berrys 185gr HBRN plated. They measure .452 in diameter.
    Seated to an OAL of 1.270

    Do you have a dead length seating die? I once tried to set up my 30-06 standard seating die like a dead length seating die and something similar happened.

    I would try to flare just a little bit more and see what happens

    Sometimes when you have the crimp part of the die set incorrectly you crimp before you complete the bullet seating and that will buckle the case like you see in the picture you provided.

    Hmmm.....I set the crimp at .471. It seems to crimp nicely.
    Would I have it set with too much crimp in this instance?
    I will try dialing it back a hair.....

    Are you crimping with a FCD or the seating die?
    Mixed or sorted casings? If mixed, I have found wall thickness difference will cause a buckling effect.

    I had some lead bullets do something similar. They wouldn't chamber as a result. Rather then pull them I sent then through lee's factory crimp die which squished them down and I shot them rather then pull. Laser cast bullets are HARD. It's the one ttime the fcd ever made sense to me.

    Edit- never mind- I missed the wall buckling. My problem was bullets not seated perfectly bulging the case wall.

    If your brass isn't all the same trimmed length, and then you inadvertently adjust the crimp with a shorter case, it will do as AA described.

    It doesn't have anything to do with how much you belled the mouths. If that was the cause, you would have shaving, and the mouths would likely be crushed also.

    I think what he was hinting at is your timing is off, you might be trying to crimp before the bullet is finished seating.

    I might be off on that, but that's what I initially got from what was said. And it does make sense.

    If that is the problem, and you don't mind adding an additional die, look into the Lee factory crimp die.

    I've had that happen on 38's. The demon turned out to be over crimping. Same type of thing with 223's. The shoulder would slightly buldge causing feed problems.

    Seat and crimp in 2 separate steps, see if that gets rid of the problem.

    Thanks for all the tips guys. Now I have some more work to do.....

    BTW, I am using mixed untrimmed brass. I may well have set my crimp on a short case.

    I load 1000's of 45 and I don't trim my brass. Its all mixed from different sheriff ranges.

    From the pic it almost looks like you have a roll crimp on these. I think you need to back way off the crimp. You don't need that much crimp on standard autoloading cartridges.

    What kind of crimp die are you using?

    I am using the Lee seating die to crimp. Supposed to do it all in one step......although the instructions for setting the crimp are almost nonexistent. A lot of trial and error.

    I began my load workup with no crimp at all and the edge of the case mouth sometimes would catch on the edge of the feed ramp. I would have to smack the back of the slide to feed the round.

    I set my crimp like this.......

    I took a cartridge that already had a bullet seated to the proper OAL and I inched the die down into the press, measuring the case mouth each time until I had my .471 crimp. Then I locked down the die and turned the seating adjustment down until it touched the top of the bullet.

    It sure would be nice if Lee had saw fit to include some good instructions. I may just want to pick up the Lee FCD die.

    Bainter, the wall thickness may vary. Example, reloading some 380 autos once with same type seating die you're using and had some buckled cases. Found that the cases were up to .004" thicker on wall thickness than all the others. I was using mixed casings. Just something to check.

    I'd pick up some rcbs dies, actually.

    But Lees instructions do suck.

    I will check that. It would certainly explain the issue.

    Does anybody use lube in a crimping die? Would it hurt to splash some Hornady One Shot up in there?

    You shouldn't need to lube for crimping. Any lube applied will have to be squeezed out.

    When I crimp for semi-auto I only use a taper and crimp just enough to remove the bell and lightly taper the brass. I measure the crimp to confirm the slight taper.

    Walkalong is an expert on crimping. He has a lengthy thread.

    You should only need to crimp just enough to reduce the bell. Do you have a factory cartridge to compare to? Can you post a pic close up pic of the round so that I can see more detail on the crimp?

    Only crimp in a seperate operation and only use a taper crimp die for semiauto ammo.

    No reason to separate the crimp step for pistol ammo. MANY of us do these in the same step.
