At the Accurate Shooter reloading forum http://forum.accurateshooter.com/index.php?board=2.0 a forum member by the name CatShooter did a Rockwell hardness test of some .223/5.56 cases. CatShooter did the hardness test to put an end to a "discussion" I was having about which cartridge cases were made of the hardest brass. (I won the "discussion) Bottom line U.S. Military Lake City 5.56 cases were the hardest followed not to far behind by Lapua.
So to answer you question Lapua and Norma make some of the highest quality brass on the planet and American companies do not come close to this quality.
The problem you will run into is Norma brass is softer than Lapua and you can not load as warm as Lapua before the base of the case starts to expand and even flow. As a side note Nosler custom brass is made by Norma, it is weight sorted, uniformed, full length resized and trimmed to length before you open the box.
Before you buy once fired brass remember this, it is mixed brass from many different lots, it was fired in many different chambers and it will NOT be uniform. Meaning if you looking for accuracy then buy new brass from the same lot for consistency and uniformity.
At Accurate Shooter the competitive shooters buy Lapua brass and they do not need to do any prep work to the cases before they are fired, and the cases last longer than any other brand because the case is harder and extremely uniform.
NOTE: Many competitive shooters where recovering their brass is difficult, will use Winchester brass because it is harder than the other American cases and has better than average uniformity. Remington cases come in last place as being the softest and the least uniform in case wall and neck thickness
Biged speaks from long experience and a deep pit of knowledge. I agree with all in his post except the bolded words:
My personal experience has led me to conclude that Federal brass is even softer than Remington. This is based on how easily the primer pockets loosen with Federal, compared to Remington.
Even relatively mild loads tend to render Federal brass useless after 5-8 firings, due to loose primer pockets. The uniformity of Remington brass is lousy, but I believe that it is a bit harder than is Federal, as a general rule.
