    Laupua or RWS. Norma is about as good.

    I've shot 15-shot test groups at 1000 yards with my prone rifle using brand new Winchester brass in 30 caliber magnums that are equal to or smaller than benchrest records. The only way I've resized them to equal what they do when first fired is to full length size them then size just the body with a special die that reduces the pressure ridge right in front of the belt back down to about new case diameters. Never got decent accuracy by neck only or partial FL sizing of belted cases. Nothing wrong with Winchester brass in 7 mag's either; sort it to 2 or 3 grain spreads in case weight; no need to prep/true primer pockets or flash holes. Turn the necks if they've got more than half a thousandths thickness spread.

    I do not believe that Lapua makes 7mm Mag brass.

    It's true. Lapua had their name stamped on Norma brass if I recall correctly.

    Lapua's website does not list any 7mm Mag brass that I can find.

    There was a time when lapua stamped 7mm Rem brass, but they didn't manufacture it. I believe it was Norma brass.

    I've always shot Remington brass in my 7mags.I've got great life with very few failures.Most of the time I shoot Winchester brass,but for this caliber,I choose Remington.

    1. NORMA
    2. NOSLER

    I am not positive but I think the only company that Norma makes brass for is Weatherby.

    How many firings can you expect to get from Nosler 7mm RM brass?

    I've heard that Lapua and Norma are now the same company. Can someone confirm that?

    That depends. If you anneal every two to three firings and only bump the shoulders and your loads are not nuclear then I would say 10-15.
