Agree, this the first thing to check.Your die is set too low. This has happened to me. The crimp part of the seating die is hitting the case mouth. Back your die off.

You buckled the shoulder with the seating dies roll crimp. The dies to low. Rise it, Never roll crimp. And ALWAYS check your brass's length. If its within 3-5 thou of max length trim it. I usually do before any other cartridge prep happens. I like to clean, trim, deburr and clean primer pockets, anneal, clean, size, clean, and load. Reason i trim first is to ensure any lip disfigurement on the case mouth by trimming is completely removed before loading, for uniform neck tension.Hi All, I'm wondering what happened here:

Trying to seat these BD2s in 7-08, and this one, the third case through, does this. We did 20 others and they all came out (and shot) fine. Is this a defect in the case, some weird interaction with the seating die, or something else I'm not seeing? I'd like to avoid randomly squishing cases in the future. This was the standard Redding seating die with micrometer.
Side by side with factory ammo, since we shot all the others we loaded up:

Also, should we shoot this? I'm tempted to see if it chambers, and if it does can we fireform this back into proper shape?
With all the new brass I've ever purchased the box had a note to run brass thru the sizer, measuring and trim if necessary. HTHHi All, I'm wondering what happened here:

I suspect that your crimp die is set too low and the roll crimp hit this particular piece of brass and crunched/buckled the brass. Try running an empty case all the way up to the end of the press' toggle, then screw the seating die down until it hits the top of the case, then back the seating die off by a half turn then lock the die in place. If you are in fact using the die to apply a crimp, then before using this die, make sure that all your brass is the same trimmed to the same length, otherwise a longer piece of brass will/can cause a buckle.Hi All, I'm wondering what happened here:

Exactly! A bigger chamfer on the inside of the mouth will do the trick Flat base bullets will catch on the brass and crush itChamfer the case mouth
I wish you lived near by. Maybe you could come help me get started. I have reloaded in the past, but for some reason, I seem to be having trouble getting up and running this time. I am SURE that it is not Old Age creeping in. LOL.I have run into this from time to time too and it always has to do with the crimp. I can't tell from the picture whether there is a canellure on the bullet but looking at the cases side by side it appears that they are the same length to the top of the case meaning the damaged one would have been too long for the setting of the crimp. Always check the length on all brass, no matter if it is used or new. There is a lot of variation even with new factory brass.
I would not try to fire this case or any one like it. Put it up on display on your loading bench as a reminder not to do this again.
Had same issue with new brass. I needed to chamfer inside neck. Apparently, it had a non-visible edge in the neck that prevented bullet seating smooth. Caused same type squish you have.Hi All, I'm wondering what happened here:

Kind of looks that the case was to long. I don't have any idea as to each case length. I use to check all my case after sizing for length. If to long I would trim the case, but my case were inconsistent for length, because I would cut back .0010th. The other cases were somewhere in between. Now I set up and place the case into the trimmer and it trims all to length every time. The trimmer I have cuts, bevels inside and out at the same time. That the first thing I do to my new case. I have just put this into my reloading process. After firing the cases I anneal, then size, cut for length. I may change it some as I go. It's another step in caring for the case. Everything is set so the case are all the same each and every time. Not require, but your reloads will be more consistent. Just one of many steps, that can be done or not. I would at lease check the case length every time, to be sure that the case isn't to long and out of speck. All the necks I cut for thickness. So that one of the reason I trim to length. If you shooting at or under 500yds, it doesn't need to be that close, but belong that it's a different thing. Hope this helps.Hi All, I'm wondering what happened here:
