Crawdog, welcome
Rocky and the others gave you good info, and i can personally attest that Taurus is rock solid on their warrenty, they will do you right by it.
MH357, just curious, your 590 and 870, could it possibly have been firing normal load buckshot 2-3/4 in a 3 inch gun??
*edited* realised by first answer was for semiauto, not pump
still it's very unusual for a pump to not extract any type of ammo, unless the heads seperate or there's internal damage to the weapon leaving a lip for the shells to catch on.
as for the .38super you can find a squib load in any manufacturers ammo, it's rare but it does happen.
I've used PMC now for almost 24 years and had no problems with their ammo, and in some cases, especially the 8mm mauser 170 PSP of theirs, you can't beat it for a factory loading.
I have seen squib loads from remington, winchester, and even weatherby once ( that got interesting, thankfully noone got hurt).
In our mass production world, things can and do go wrong, usually if you work with them, they make it right though.
