Checking ammo...

With all of these defective ammo threads coming about lately I figured I would ask, "What I should be checking to see if ammo is any good?" I mean I normally check every round visually, like a quick glance over, but other than that I do not do anything else. Should I be? I mean some of them are obvious with the shells bulging or something as they are in the other threads but other than that what should I be looking for. Some people said that they were set in a little too far and whatnot. However, I am not sure what that means exactly. Can someone explain? Thanks in advance.

When they are referring to "set in" they are referring to the seating depth of the bullet into the shell case. One that is in too far can cause a spike in pressure that could be unsafe.

^^^So, how does one know what is correct? Or, how much seat in there should be? I mean I could lay them all out on a table and get my micrometer out but lets say the whole box is set in too far and I do not have a correct one to go by, is there some kind of standard somewhere?

Usually you can find an over all length on or in the box somewhere, on the makers website or worst case on the Internet. Wikipedia usually has that info but only for the standard size/shape bullet you'd find for that round.

Having the OAL should tell you whether the bullet is set too deep or not.

No manufacture publishes OAL on the box, or on the website.

The best you can do is open a box and see if all 50 rounds are sticking out of the packing the same distance.
If they are you can assume they are all right, or there would have already been a recall.

Other things to check are primers all seated below flush, and right side up.
And case mouth tears or curls that would prevent chambering.

Then?
Choot'm Lizabeth! Choot'm!

Wikipedia stats cites standard sources like Hodgdon's reloading manual, Cartridges of the World, and powder and ammunition manufacturers.

That's hard to say unless you have the same rounds that you're sure have the correct OAL. One of those things I guess you just have to use your best judgement on! I think if I had a suspicious box of factory ammo I'd toss it and cut my losses. Its not worth the risk, but that's just my opinion.

The only way you can KNOW they are correct is to load them yourself.

With factory ammo, beyond a visual check, you just have to trust it.

The internet is an echo chamber. There are probably billions of factory rounds of ammo sold every year in the country, and 300 million firearms. Nothing you read on the internet about them is likely to be statistically significant.

Keeping the gun relatively clean and functional, and being proficent in terms of knowing its operation, and/or being at least savy enough to recognize when something goes wrong (squib, etc) will save you from 99% of likely problems.
