I've done similar with .223, but not that badly. Congratulations.

Yup ... That's what happens when you eat too much spinach before you start reloading

Had it happen a couple times ... some chamfering usually prevents it.

Also, no idea about yours, but mine only did it on cases that were nearing the end of their reloading lifespan. I think they were stretched and thinned to weaken them as I don't use any pressure when seating.

I did it with 300 WSM the other day. I did it while setting my seating depth on a new die, had it screwed in a weee bit too deep

Winchester brass by any chance??? Friend has been telling me to say away from the newest win brass full of flaws and light by weight compared to stuff produced even three years ago.
Just his words I have no proof??

Now that's artistry! I think everybody's done that, but not so completely.

Chamfering and tiny bit of lube inside the neck will help prevent such in future.

You can buy special brush sets for inside lubrication, but somebody on this forum came up with a brilliant idea - a small jar of birdshot with a squirt of graphite powder in it. Shake it up to mix and then just push the necks of the cases into the birdshot to give a suitable amount of lube. Shake it again every so often to keep the graphite distributed.

I did a 243 a little worse than that this fall. Something else to put on the "mistakes and odd ball" shelf.

Conversation piece for the man-space. I keep my goof ups as reminders to stay focused!

Yup - I use one fo these with graphite powder:

It's actual name is a Case Graphiter. Put the lid on, give it a shake, then you are good for a dozen or so rounds. I do all of the rounds just prior to filling them with powder, but after priming.

Have you come up with a name for your newly designed wildcat cartridge yet ??

 

[Mad_Mikee]

Looks familiar. I had the same problem with a 375 Ruger and most recently my 300wsm.

I accidentally did that to some 30-06 cases on a buddy a while back. Had the seating die screwed down way too far. I've also had it happen with brand new Remington 300 win mag brass. A little chamfer on the case before seating fixed that up.
