At present, I see one parts vendor for my bridge involved in 3 of the last 3 catastrophic failures in my industry with 3 different agencies with 3 different projects, with that being the part that failed every time. And with a seemingly higher frequency of a warning sign deformation behavior. That's a huge red-alert, just so you know. And then I see a difference in construction philosophy that happens to show up at the location of the failures. The other vendors in the same usage aren't failing and aren't so readily showing this strange deformation warning sign? Yea, that vendor is gone.
This explains your abundance of caution applied to Lapua brass. You can't take a chance on being wrong about a vendor's failure data. Especially if you see a trend.
