Again, I think that you misunderstand me..... I am not trying to be critical of Hornady product in general.... simply that I had issues with the 375 Ruger brass that I purchased which they had produced.
I use a lot of Hornady products both brass and bullets, some of the best brass I have used in 6.5X55 and 303 British for example have the Hornady headstamp.
I don't know what you are trying to prove with the Norma brass in 6.5X284..... I have some of that also but that doesn't tell me that Norma is making 375 Ruger brass... does it ??
That post wan't directed at you or anyone specifically, just that it seems to be generally assumed that Hornady makes the 375 Ruger brass for Nosler. If Norma makes 6.5-284 brass for Nosler I'm pretty sure that they could make 375 Ruger brass as well, one would have to try it to find out and it could be the solution to the "brass problem".
