Re: new big case manufacture
I have a 416 Based 30Cal Wildcat which I've shot Norma brass in. I have purchased 3 lots. The First lot was used for 1400 rounds and some of the cases were used 45+ firings. Those cases are still OK to refire and may get the necks cut off and reshortened into a 6.5mm/416. Primer pockets are fine. Fired 210gr Bergers at 2750-2900fps from a 27" barrel with them. All are still fine.
Lot # 2 was fired no more than 5-6 times before having about a 50% failure rate. Heads seperating... They're pretty much junk now. There may have been a recall on them because the WSM brass has the same problem and they were recalled.
Lot # 3 is looking real nice again. I've only got a few fireings on them though so I can't say about the quality yet. They LOOK ok so far.
As for the brand you speak of, I can't say but I'd look for Norma brass in the 416.
If you have something that you disassemble and reassemble enough times, sooner or later, you'll have two!
