I just order some norma brass in 7 rem mag. My understanding is it is a hard brass and has thick necks. Can someone verify that for me? I hope this is correct. I have never tried norma before. I have a long chamber that destroy's federal cases in about 3 firings. Thats one fls, then neck sized, then bumped and its scrap. Rem brass is doing ok so far. Im bump sizeing it only. It seems to be working. Im not haveing to trim. It actually got a tad smaller after the third fireing.

Whats your load? I bought 100pc of norma and when they were dead i went back to win brass. Norma had a .314-.316 loaded neck and lasted 3 firings and win lasted 8. Not worth it for me.
If your chamber is long make sure your dies are set up properly so you dont over work your brass. Or get it set back by a gunsmith.

Dont tell me that! That's not what i want to here. They advertise it as hard brass and tough to withstand numerous firings. GREAT! Sounds like federal brass. My length shortened by .001 on the 3rd firing. I think i got it right. Very little brass did i have to remove.

I use Norma Brass for 300 Weatherby. It's actually soft. I got ejector marks with start loads. I worked up to max and above max and have 7 firings so far. So, just because brass is soft, doesn't mean it won't last.... I don't even pay attention on the ejector marks on Norma brass, especially when the primers are nice and round and the velocity is in check...I would not want "hard" brass, I anneal so it won't be hard... Don't worry about Norma brass, you will get good life and consistency with it.... I won't use any other brass if I don't have to...
Federal brass isn't even in the same ball park as Norma brass, I will say, I use Federal brass for a very accurate MAX load with 178 Amax in 30-06. And have no problems what so ever, I have 10 firings on the latest lot, and primers are a little loose but I expect one or two more firings befor I scrap them, they would probably go more, but I don't risk it, not with cheap brass...

I believe each caliber may be different. I have a 300 saum with norma brass and running it hard gives me 7 loads before the pockets loosen up. Same as gohring said, my saum brass shows ejector marks with any load as well.
the 7 mag brass gave me 3 reloads of 68gr h1000 with 180 bergers. In the win brass i used 69gr and it lasted way longer.
I wouldnt stress about it. Work up a load and keep an eye on pressure signs. What bullet are you wanting to shoot? I loaded for both the 168s and 180s and came up with loads that are pretty close in just about any 7 i tried them in.

If you are trashing brass from a long chamber after three firings, you have a big problems. Trying to put a bandaid on it by finding a brass brand that prolongs the obvious is not a good idea. I don't think you will ever get good life out of any brass... The Remington brass is a good choice, it seems to be thicker, it just feels heavier built...
I find Norma to be about the best bras available. I load 7mm, 300, 338-378 Wby, 270wsm and 375 H&H in Norma brass I have 8 firings on the 7mm Wby loads and going strong. Weight is consistent as is thickness. The flash holes are the best of any brass I use. Certainly can't say that of the Winchester junk out there. I would double check your sizing, I full lenght and back the neck down .002 to avoid overworking. Certainly watch pressure.

My Norma 7 mag brass - 100 pcs is on its 5th firing and I have not had to throw out any yet. As with ANY brass if you run HOT loads brass life will be short.
160gr. Sierra SBT 59.5 gr. Imr 4831. 2850fps. Thats always been the sweet spot with any loadings.
sorry you misunderstood me. Disregard those numbers. Those are my headspace measurements from my gauge. ?.026 would be the shoulder bumped back.001. The ?.027 is the shoulder is just barely kissing the chamber. After i get my headspace measurement i just pay attention to the last to numbers after that. I couldnt remember the whole measurement at the time i posted that. Barely touching the chamber lets me camover without resistance. Ive read the shoulder shouldnt touch the chamber because it want come to rest in the same spot each time.
