Most of those spent cases show pressure signs, especially extractor marks on the heads of the cases.

Take the remaining back to the supplier and ask Hornady for a please explain.

I'd also get your rifle checked by a gunsmith to ensure there is no issue with headspace etc, especially if it's a new rifle.

This may help explain head space.

Can you post some close up photos of the empty 150gr loads just to be sure there are no early signs of excess pressure with this ammo too.

A good gunsmith can advise you if there is any damage or if the head space is within specification and what can be done to fix anything they find.

Over max pressure signs, stop firing that ammo.
I use superformance powder in hand-loads and while it it can be great for velocity there is some extreme batch variation and I have ruined a bit of brass as a result.

Check your bolt face for gas etching - a burn ring corresponding to the primer outer circumference.
Potentially a further complaint at the shop you bought the ammo from.

Mate there's excess pressure signs in this brass too.

Especially the bottom right hand case and 2nd down on the right have leaking primers and extractor marks in the head stamp.

Others have extractor marks in the head stamp.

I'd take all your ammo back to the supplier along with your rifle and ask for an explanation.

Can you post a photo of your bolt face.

That looks like the same hornady brass? Can we see the Winchester ammo you fired that was ok
