Yes, those are off center primer hits, but the rounds should have gone off fine. My S&W Mod. 76 where the firing pin damm near hits all over the primer and goes very deep, But it all wise goes off.

I would contact Hornary right away and tell them what happend. This sort of ammo, or any ammo, should go off every time. Save all the bad and unfired ammo and the box so they can have all the lot info. Sounds like a big Recall is in order, But a recall saves a life it's worth it.
