180gr @ 1059 fps doesn’t seem the least bit impressive for 10mm - I am still sitting on 600 rounds of GA Arms .40S&W 180gr x 1000 fps ammo (180 Power Factor) from many years ago.
I first assumed overpressure, but looking at the fired primers around 3:05 I don’t see sigs of primer flattening or primer flow where the firing pin struck the primer. I also have no idea how hard those primer cups are, but there is no obvious sign of overpressure other than the case splits.
My guess would be a combination of a faster-than-optimal powder combined with an issue with the brass cases.
The chamber of the gun used might be a contributing factor.
That’s about all I can come up with.

Are you now, or have you ever been a member of the Doodie Project?
Search "prograde brass" and you'll find this isn't new. They've had some runs of brittle cases.

Beware of my temper, and the dog that I've found...
Another reason to stick to big-factory factory ammo.

Not another dime.
Prograde brass is to brass what Promag is to magazines. Run away from both.
Don’t blame me. I didn’t vote for that dumb bastard.
