“Hey, my shits way over pressure. Any advice?”

Use it better.
This is snipers hide, if you’re not at 80k psi, you’re just not trying hard enough!
Shot factory hornady ammo an it does it to about half the rounds. Shot nosler factory ammo an those are all good
Is this a new gun? Has it done this before? Do you know if the headspace is correct, and the freebore not unusually short? Could you have a carbon ring that is increasing pressure?
When you loaded them up, did you go straight to 78 grains? How fast is it going? Have you tried backing the charge off or going to a slower powder?
I always thought Nosler brass was mediocre. Peterson to the rescue.

28 Nosler
The 28 Nosler is a great long-distance big-game caliber that takes advantage of the newer, high BC, 7mm bullets.

You do understand you came on here and pulled your pants down?
Whether you are into pressure by say saami standards or not, you are definitely pushing the limits of your brass if you are expanding the case heads that much with one loading. It could be the brass, supposedly Norma makes some brass for Nosler, if it is Nosler brass. But then again, maybe a good portion of the damage was done on the first firing, you did not say if you farmed brass from factory ammo or what.
Buy some new brass and chalk it up to a learning experience, you were probably a long ways from a catastrophe. You gave us little to trouble shoot with also, were the pockets gassed?
Yes went straight to 78 grains. I guess i will back it down a bit. An i did order some Peterson brass. Just waiting for them in the mailWhen you loaded them up, did you go straight to 78 grains? How fast is it going? Have you tried backing the charge off or going to a slower powder?

As you now know, that’s just a bad practice. Peterson brass usually has a little less capacity than typical domestic brass. You would have been in a worse situation if you’d started with it at max charge. If I’m loading up something I’ve never loaded before, new wildcat, etc, I’ll load up a ladder in one grain increments. Usually it’s 5-7 rounds. Use them to zero, get velocities, and maybe run into pressure. Then go home and load up some safe charges to group with.
Different brass, lot of powder, chamber differences could easily make a book charge well over brass limits and if your smoking pockets in one firing your definitely over the limits of your brass.
My only experience with nosler brass was with my 260 and honestly necked up Winchester 243 brass was far superior in my opinion.

May I suggest some good reading material?
