Like others have said, it's almost certainly too much crimp. If you have proper neck tension no crimp is necessary on a bottle neck rifle cartridge.

If you like Hornady dies I would suggest you invest in their Match Grade Bushing Die.

I assume you are trimming the cases as part of the reloading process as well?

I would suggest that you clean your brass as well, dirty brass is not good on dies.

It gets cleaned, lol, just not polished. I do plan on getting a tumbler though, as I stated earlier.

Yes, the cases are being trimmed as part of the process.

I'll start with backing off on the crimp and see where it gets me.

I'd just not crimp at all. Most people don't crimp bolt action precision ammo. That heavy rifle doesn't have tremendous recoil. Crimping is likely adding a variable with nothing but downsides

I'm with you on this one hatt. I reload .338LM, 300 WM, 300 WSM, 300 RUM, 308 Win, 6.5X55 SE, 264 Win, 7mm-08, 7mm WSM, 7mm Rem mag, and 325 WSM.
I neck size only when possible and don't crimp any of the above.
Mag primers in all.

I’m late to the party, but I see buckled shoulders. Those are coming from _way_ too much crimp, or from defective parts. Stop crimping altogether for a few rounds, then start with a LIGHT crimp and see what happens.

The crimp was set just via the instructions that came with the die. As I noted, it only affected 5 out of 50 rounds but I'll be backing it off and seeing if that improves things for the next batch.

As I'm thinking of it: I've buckled shoulders on rifle brass exactly once that _wasn't_ from trying to crimp too much. That was when using new Hornady brass, bullets, and dies. A fairly small percentage of the brass buckled the shoulders even when I had zero potential for crimp. In that instance Hornady replaced the lot of brass for me. In this instance, since you're using fired brass, the brass itself seems relatively unlikely to be the issue, but I suppose it could be?
