That's just pitiful quality control...thanks for reminding me why I've been reloading for 30 years. Personally, I would send that box-o-junk back. A few dented rounds? Stuff happens, no big deal...but that many rounds? Looks like someone put all the rejects into one container to me.
I don't blame you bro', I would be screaming at someone on the phone.
Especially about the loose and angle seated bullets!
