Do you then bin the entire batch; or only the cases in question and just keep an eye out on the rest; or milder loads, etc?
Once one in a batch has failed definitely start keeping an eye on the rest for failure, but it doesn't mean you absolutely must throw the lot out.
Case consistency and flaws vary so the difference in life between 2 cases in the same batch can significant.
Some guys don't batch at all, they just check each case individually and could have new brass in with 20x fired brass. As long as it all checks out there is no harm.
Saying that though, if you're worried or just don't want to worry about it throwing the lot after a few start to fail makes some sense.
If you get 15 - 20 shots out of a batch then a few fail and you toss the lot, it's not like you haven't gotten your monies worth from them.
