Norma has the longest and best standing reputation for the 300 win. I have some for sale. PM me if you're interested.

Lapua is better, but they don't make it anymore.

Seen some people liking the ADG recently, but I don't want to be a guinea pig trying something new.

Take a look at what benchrest shooters use if you want the best consistency.

It is never a mistake to use brass from the parent company. It is a sure bet that the cartridge was developed with parent brass. With the outsourcing going on these days, the headstamp on the brass may, or may not, be the same as the manufacturer.

I think I’ll try some ADG. A guy had recommended to me the gunwerks so if it’s made by ADG that should be a good place to start. Rky Mtn Farmer, if you don’t mind give me an on how your Peterson brass does when you get it. Thanks for the all the recommendations!
Sorry it took me so long to let you know about the Peterson brass, been busy the last couple of months. I finally got a chance to load up some and test them out. I found that the Peterson brass is very consistent and loaded really well. The same load i was using with Norma brass ended up grouping great with no flyers. Also increased the velocity by 85 fps. I have been fighting flyers with my norma brass. Ended up printing .78 MOA six shot group at 100 yards. It was a little tighter, but i shot a sixth shot just to see if the group would stay consistent. I am pretty happy with the results since that is with a factory barrel. That being said, I think you would not be disappointed if you bought some Peterson 300 Win Mag brass.

Some of the best brass on the market right up there with look Laupa and a, tad better then ADG.
I use Peterson brass, exclusively in several calibers no complaints

Win brass has done pretty decent for me. I push the dog snot out of it!!! I have used Norma before and would like to go back to using Norma. I just have to redo my load data.

Look for some older blue bag Winchester 300 wm brass if on a budget. Excellent brass though. I can swap load data between Winchester and Gunwerks brass. Lots of peeps say ADG makes Gunwerks brass, and maybe they do but I had different results. My ADG brass load was 2 grs less than Gunwerks load using H1000 and 215 hybrids. ADG brass would max out at 2940 fps and my gunwerks load pushed the 215 at 3050 fps with no pressure signs.

I would look for:
Gunwerks
ADG
Winchester blue bag or older
Nosler

Great luck with Nosler here. Still wishing Lapua would start selling 300 WM brass..
From what I understand Lapua is indeed going to start selling 300wm brass.

To the OP, I've been using Norma brass and it's performed great so far.

Having really good luck with ADG here, I've had loose primer pocket issues with Norma.

I've had great results with the Winchester brass. It's been so good I'm not willing to try anything else.
This is my experience too. I tried Remington and federal and neither did well through the reloading process. In my experience they also cracked necks earlier.

I have annealed the Winchester at least one time. They pulled through the press like new.

I’ve tried Remington federal and Hornady. Nosler is still my favorite

I have new Nosler brass but I still had to prep the cases and now I can't find it for under $100 per 50...they should just sell it "unprepped" although it'd still have the same asking price.
