300 WM Brass options

[Bigwheels]

Gentlemen I've been using Win brass in my 300 for years & have several hundred with 7 firings on them. I think I'll get a few more out of them but obviously they are about done in. So I bought a couple 50 packs of new Win brass & I'm pissed.
A full 1/4 of them had heavy machine marks & split/crushed necks. Several more wobbled when set down on a flat surface & even more had .003-.004" variance in wall thickness @ the necks.
So since Lapua doesn't make 300Win Mag brass any more & I've heard of problems with norma being soft what is the best bang for your buck 300Win Mag brass now?
Thanks.

Was just commenting on Peterson in another thread. Try Peterson. A buddy and I ran a test on it. Very consistent, and very strong.

Ok thanks. I just looked into them & they look good. When I clicked on the order brass tab it redirected me to Graffs but they're out of stock. Is Graffs the only place?

 

[Supersubes]

I believe grafts does all their distribution. Didn’t know the peterson site redirects to grafs though. Not sure on another vendors. Pretty sure grafs will take a backorder though.

Thanks. I also found them @ optics planet but they are also out of 300Win Mag brass.
Do you have any further test results of this brass to share? I found your previous posts but couldn't see the attachments. Especially interested in the neck thickness variance & belt expansion after firing along with longevity.

Another vote for Peterson. Shrank my groups by half.

Only on the second loading so not useful comments.

I can't seem to find the Peterson 300wm brass on their site. I remember emailing them about making 7 mag brass and they said maybe.

Pretty sure Nosler has an offering. I Use Nosler across the board and have used the shit out of it with my 300 RUM. It’s just good stuff.

I keep hearing quality reports from ADG and supposedly they're coming with 7 SS brass so i'll be giving them a try.

when i was shooting a 300wm i used nosler brass...i got 17 loads out of one batch but most times it was 12 to 15 loads.

Anyone use Prvi Partisan brass? What little I've seen it looked ok.

Date stamped FC is pretty good. You'll need to reduce your charge vs win.

Jeff Look at ADG Brass, very uniform. I can't verify the durability as I'm on my 3rd loading. Sig Sauer is readily available too, these are much better quality than the Winchester CRAP. I had similar results recently with Winchester 300 WM brass. Culled about 25% out of 200 cases. The remainder shot well, but no quality control as new. Creases, cracks, dimples etc. I did complain and returned faulty brass for a refund. The primer pockets in the ADG brass not super tight as new with CCI 250's in my batch, but they haven't loosened or leaked. Running 208/210's @ 2900-2980. 3-4 grains difference in weight total across 50 cases IIRC.

Ive used winchester, remington, nosler, norma, Hornady, and RWS.

The Norma stuff, which is supposed to be the same as Lapua, is pretty damn consistant.

The RWS stuff is super heavy duty.

The Nosler stuff had serious quality control issues; about 30% of the belts were so off the bolt wouldnt close. (This is when I learned to start checking belts, and that shell holders are not actually the close to the require belt tolerances.)

Winchester used to make Norma brass. Not sure if they still do.

Winchester brass had generally higher case volume deviation, but like all other brass if you weight it and sort it, it was fine.

I don't think Peterson has released 300wm brass yet. Everytime I ordered 338 brass the 300wm brass said coming soon. Could be wrong tho.

I have ten boxes of Peterson .300 WM brass in my reloading storage. It was released some time ago.

I've seen it on their website before but it's not even listed anymore.

I get the best accuracy, but not the best durability from Norma. I bought a few RWS brass at a yard sale of all places and it's tough as nails. No matter how hard I beat on it , it doesn't show pressure signs. I have to rely on my chronograph to keep me out of trouble.
