The reason there are so many Ruger upgrades is because they're necessary.
Quaib is that my imagination or is the primer pushing out on the case on the far right in that first pic? It looks like the cases are sticking in the chamber of your rifle and the extractor is ripping a chunk out.I would contact Hornady about this and see if you can't get a refund or replacement for that ammo, looks like a good idea to stay with the Remington and make sure the chamber in your rifle is clean.
heres how a gas operated semi auto works. theres a port in your barrel that allows gasses to travel back to the bolt and push it to the rear. there is then a spring that pushes the bolt forward stripping the next round and seating it in the chamber. when the round goes off the case in turn swells up. if the bolt is forced to the rear before the case has a chance to shrink back down it will rip the side of the case exactly as your pictures show. this is common with people who shoot carbine length ar15s and steel cases. I would doubt your extracter is damaged. keep to the lower pressure rounds and you should be just fine. im not sure how your buffer system works but i know a lot of guys will run a heavier buffer in their ar's to help slow the system just enough to keep this from happening.
