Bought a GUNWERKS MAGNUS 300 about a year and a half ago, great rifle. I even took their Long range shooting class with an antelope hunt and well worth the price. I had a chance to talk to their guys and they said to use Norma brass, and this is where it got confusing, because when they sent the ammo with the rifle, it was Hornady brass! ??? I have been using Nosler for most of what I shoot, and still do. Their weight sorted brass has always been within .6grains of each other making for great consistancy and accuracy. Tried Hornady just like they used with their same load specs and did not notice any difference, but note that I used the Hornady 50 case packages and they had good consistancy. I then bought it in bulk because of the price and that is where it went down hill. Had up to 6 (six) grains of discrepency between cases even after preping and a lot of damage due to the brass case weight during shipping. Buy small quantities in the pre-preped condition. It is money well spent. My loads have been using both Hornady and Nosler brass, 74 grains of 4831SC powder, and 190 grain Berger VLD or Hornady 200 grain ELDX with no noticeable difference out to 600 yds. Beyond 600 the ELDX has more drop of course. Able to get 5/8 MOA with both at 100 yds.

I have contacted both Laupu and Peterson recently. The reply from Lapua is "Right now we have no plans to bring this brass back out again. But requests have led us to consider it very closely. This is the best we can say right now." I immediately gave my request!!
Peterson replied and said they hope to have 300WM available again this fall.

I have had very good luck with Nosler brass for my 300 WM. I am on the 6th loading of the first 100 cases that I started with in 2014. I recently bought another 100. Loaded them without any case prep and they shot to the same point of impact and the same FPS (chronographed) as the older brass. When I first bought my 300 WM, I bought some cheap Remington Core Lokt ammo to get it on paper and break in the barrel. Those cases were also good for 5 reloads. Then I decided to go with Nosler, so gave away the Remington brass. I also use Nosler brass for my 270 Win. I have not had any incentive to try the more expensive brass, so can't make a comparison.

Early 2017 John Nosler told John Barsness that they made the majority of their cases and eventually all Nosler cases will be made by them. That was 18 months ago so whether they make all of their own cases now is a good question.
I am interested. How much are you asking?

Norma made Nosler brass forever maybe not now but I doubt it.

ADG 300 WM brass came back in stock this afternoon. I just ordered some to try out even though I have had very good success with the Norma brass I bought in bulk in the past from Midway USA.

Unfortunately they haven't made it in about five years or so.

I've used Norma and R+P brass,with great results don't bother with weighing brass, just internally debur the flash hole. I've never neck turned either but I annealed every time. Plus trim the cases.
I've had multiple loadings ( about eight or more ) use a Lee Collet Die.
Awesome accuracy and brass life with both and I use Berger 230 OTM Hybrids.

I've been considering a couple of Lee collet dies for necking down .375 Ruger to 6.5 LRM. Do they make a collet type necking die?
Not that I know of, but they do make custom dies for a reasonable cost. Or you may be able to purchase a 375 die and a bunch of progressively smaller inserts.
