The brass is still a bit soft and I have shot more than a few through mine. They shoot well with good loading practices. I can't speak to the factory loads as I've never bought/fired any. The Nolser steps up for usage in spades if you convert the Hagar brass to it. What we've shot with it is outstanding compared to the factory Federal stuff. Loading the Hagar in the 22-NXS with case life already at nine firings with tight pockets speaks well to it and a cross over to the 22N is certainly reasonable.. That tall waisted rebated case head is not helping at all for longevity.
Midway does those clearances all the time and then three months later has the ame stuff back in stick and three months later closes them out again. I've picked up more than one Redding bushing die in 6.8 because of that and saved some nice con. I also picked up 300 pieces of the Nosler bras at give away prices so if it wears out fast I don't shed too many tears.
I think the N has a step up on the Valkyrie if you stick with the light bullets thanks to case volume. Both are SAAMI'd at 55,000 and that is a bit detrimental in comparing them to a 6.8/Hagar variant like that can run at 57,500 with no issues. The Nolser case walls are very thin and this is where e it picks up it's volume but that is also working against it in the upper pressure ranges. I did pick up a VALK. barrel so I can run some side buy sides with it and if Black Friday generates some extra uppers I'll have Ritch build one for me. I'll be able to run 22X6.8, 22 Nolser, 22 NOSGAR, 22 Valkyrie and 22-NXS all in teh same length tubs. That will make for a long couple days on the range but should generate one heck of a lot of comparison data.
If you build yours let us know how it does.
