[QUOTE="Pdvdh, post: 1219829, member: 4191"] No, I don't have any Norma headstamped brass. Not even any field pickups that I can think of. I have some Weatherby cases that are supposedly manufactured by Norma. These are cases I don't use any longer but remain in the reloading room. However many guys say the Norma headstamped brass is tougher than Weatherby headstamped brass. The .378 Weatherby brass I necked down to .338-378 Weatherby did seem rather soft/weak (and darn [I]expensive[/I]) 25 years ago. Lost the primer pockets pretty quickly, even with what appeared to be rather mild loads. I've also seen factory fired Weatherby cases where the primer pockets expanded on the initial factory firing of the cartridges, and with plunger marks on the case heads. So it appeared to me that Weatherby wasn't concerned with the reload-ability of their fired casings. One reason I sold my 338-378 rifle and moved on to 338 Imperial Magnum, and then 338 Edge, and finally (today), 338 Lapua Improved. The RWS 404 Jeffery casings have pretty strong primer pockets, but the brass was soft enough that the end of my bolt was getting trapped in the interior of the case head after two hammer blows. I closed the bench vise jaws around the end of the protruding bolt and then twisted the cases to get them separated from one another. It took quite a number of hammer blows to get the R-P 7mm RUM primer pockets to tighten up. Which surprised me because R-P RUM cases have an average reputation for primer pocket toughness, yet the case heads were resistant to deformation when I hammered on them. [/QUOTE]
