On rifle brass, we try to be very specific when we say that we don't process it for customers by default. So if you don't process it or pay us to do it, it gets loaded as-is. Our process is to typically spot check 2 or 3 cases, and if they are under the max, we'll load them. That is not the recommended trim to, that is the max case length allowed, which is not the same thing.
So, the fact that all of our cases in the Value Line, which we processed, worked fine would seem to indicate the issue is with the brass. Now, we expect our customers to do their due diligence when sending us brass, which is why we call out rifle specifically because we can't sample every case and pistol brass almost never requires trimming. It is a balance we have tried hard to strike and as in this situation, isn't always easy one as the responsibility for the brass is ultimately on our customer's shoulders.
Regardless, if the ammunition bulged, it would not pass our gage. With customer brass, even if the round doesn't gage, we put it in a bag, notate that it didn't pass, and send it back to the customer. Same goes for blemishes and the like, things we would reject in production, we give back for the customer to decide what to do with. If 90% of your cartridges failed the gage because the 2 or 3 the loader checked were okay, that's one thing but it should have been noted.
That is my concern, which is why I'd like to get it back, our gaging regimen needs to be checked carefully on this and we will do that.
If they don't gage, then part of the fault is on us and we'll do what we can to salvage as much of it as possible and replace what can be replaced. It may highlight a weakness in the process that we can improve on and hopefully get you some ammunition that may still work.
There is no Hazmat for ammunition, just draw a diamond on the side, fill in the top and bottom with black, and ship it UPS or FedEx. You can also label it, "ORM-D, Cartridges Small Arms" but the new standard is the diamond indicator. Just mark it RMA-YOUNG so we know what we are looking for.
We'll get to the bottom of it and resolve this in a positive manner.
