Well,
If you're a personal friend of Mr. Pi, then go for it. I doubt I could be of any help anyway since I fired all that stuff and switched brands so I have no clue as to lot numbers and such. However, the 32 was very repeatable so I suspect it could be duplicated even today.
I'm very happy with switching to ATK products as they seem to have good quality control (maybe not Hornady good, but better than anybody else) and have the best bullet designs around.
That said, I'm impressed you are that concerned about CorBon's products.
