those dented rounds would work fine.
I've shot many rounds of .303 and 7.62X54 that had cracked necks and dents.
furthermore, checking your rounds right when you buy them is a waste of your time.
I've got a more efficient suggestion, check them when you are loading them into magazines on the day of shooting.
you check them when doing that anyway, since each round spends several seconds in your HAND.
