I'm in the process of rebarreling my 8mm mag, I have a significant amount of nosler brass, but I noticed that Peterson has basic brass available for it, has anyone had any experience with reforming this brass? Is it good enough to form in 1 pass or should I get another die.

Yes. I've used new Peterson brass, and then up to 3 re-firings of it, in my 340 Weatherby. It's very good brass, and I had no problems with resizing, primer pockets, etc. I annealed after every firing though. Be aware that they may be thicker-walled and therefore may have slightly less capacity (mine were), so one should drop the pow charge down and work up again.
I shoot Peterson brass in all my belted mags and it's great. I noticed the new basics brass is more expensive than their 300win mag. If I was staying with 8mm Mag cartridge, I'd buy the 300WM and neck up.
IIRC, @Bghunter338 has experience with it, too, but not necessarily for 8MM RM.

I have Peterson brass that I have 7 firings on, and brass is still going strong. One thing I have noticed, I'm not able to put as much powder in the brass compared to other brands.
Primer pockets seam to be pretty tight on all 7 firings. Don't have many bad things to say about it honestly.
Good luck!

Oh if that were only possible, 8mm rem mag is way longer than the ol 300.

Are you staying 8mm rem mag or are you changing to a different caliber??
When I formed to 7STW it only took one pass but I annealed it first

I'm staying 8mm, I have a new 1-9.5 barrel and a train load of new 221 hammers I haven't got to try yet. I thought about switching cases but this one is easy to headspace off the shoulder so switching doesn't gain me much.
I seen this Peterson brass and hoped the stw guys had tried it.
Duh! Sorry I should have known that, I load 7mm STW and I use necked down 8mm mag brass because it's long enough and easier to find than 7STW.

I have some Peterson but very little, I am still waiting to get my STW to get home.
I just got a 100 count box of 8 Remington mag Bertram brass that I have to reform to 7mm
