I just recently purchased some Norma .223 Rem brass and have started working up a fire-forming load with it. I began checking it out by weighing 50 cases. The overall weight range was definitely narrower and more uniform than Lapua, especially the most recent Lot of Lapua .223 Rem brass I purchased, which was terrible. The Lot of Norma brass I received is noticeably lighter than Lapua (~5.91 g vs ~6.19 g average case weight = ~91.2 gr vs ~95.5 gr). Some of the weight difference is within the case necks (and therefore likely the case walls also), which are visibly thinner than Lapua. If some portion of the weight difference also lies within the webbing/casehead region, I'm not sure how well it will stand up to stout loads such as I typically use in F-TR with 90 VLDs. Time will tell, and fire-forming the Norma brass at a reduced charge weight the first time may help work-harden the case head a bit. The case walls/necks appear to be very uniform in thickness. As expected from the weight difference, the Norma brass averaged ~31.4 gr internal (water) volume as compared to ~30.8 to ~31.1 gr for various Lots of Lapua brass. Unlike Lapua brass, there is visible flashing inside most of the cases from punching the flash-holes, which will need to be removed.
I have only fired a few loaded rounds with the Norma brass to establish a baseline and calibrate QuickLoad. Nonetheless, the shots groups very well, even with a load that was not optimized in any way, shape or form. I view that as a very good sign, because I've tried another brand of .223 Rem brass that never exhibited the same precision possible with Lapua brass even with optimized loads. In fact, I'm going out for some preliminary load development with the Norma brass as soon as I finish typing this post. The main reasons I purchased the Norma brass were because A) I had heard good things about it (anecdotally, of course), and B) it was on sale at a price approximately half that of Lapua brass, so I figured even if it won't hold up to the stout loads I use in F-TR, which typically kill the primer pockets of Lapua brass in 2 to 4 firings, I can always load it for other purposes. If I have any further observations that might be of interest after today's session with the Norma brass, I'll add them here. My overall initial impression of the Norma brass is that it is very well-made and consistent.
