I bought 150 pieces of Sig Sauer .308 brass (all same batch) a while back and finally got around to loading it and shooting it last week and thought I would share my experience.

First off, Ill say that Im no expert reloader, but I do like a good accurate round, so I try. I know I do less than lots of guys here, but I dont have trouble getting .5moa out of my loads in my factory savage rifles, and thats good enough for me.

Anyway, before loading, I randomly weighed and measured about a third of the brass.
I was pleasantly surprised that EVERY one I measured was 2.005 on the nose.
As for weight, they were all within a grain of each other (half grain either way of the "average")
and they were about 3 grains heavier than the remington brass I have been using, which had about a 4 grain spread in weight. The Sig is much more consistent.

On the range, I got an extra 50-75 fps over the remington brass with the same powder load. primer, depth etc., depending on the bullet.

I used my normal loads of 43gn IMR4895, and 43.5gn Varget, no pressure signs

I got 2795fps average with 165 SST's,
2785fps with 168 TTSX
2750fps with Berger 168 VLD Hunting
2767 with Hornady 168 BTHP Match

All shot .4-.6 moa

CCI Primers
Savage 110 Tactical with 24" barrel, 10 twist.

Overall, I'm very happy with the consistency of the brass. Cant speak to its longevity yet, but like I said, no pressure signs usually gets you pretty long life. Especially on the lowly 308 haha.

I couldnt find much info on the brass, but I bought it because I got a great deal, and I hope maybe this helps someone who was looking into getting some.

I had the same results with 22-250 brass. I used mine to turn into Ackley rounds. I neck turned but probably didn't need to. I just wanted to control doughnuts and not having prior experience with Sig stuff, figured it couldn't hurt.

Pockets are great after a fire forming and two loadings. I think it's great stuff.
 
I think Atlas Development Group ADG makes that brass... at least I read that somewhere.

I'm planning to buy some ADG brass soon for my Rum

I haven't gotten to neck turning yet. It basically keeps the brass thickness the same at the neck for consistency, right?
Like I said, I'm no expert and havent been doing it all that long.

Maybe the Sig brass are thier seconds? I only say that because the Sig is about $15 less per 50. ADG looks like some nice brass.
 
I turn for maximum consistency. I mainly bushing neck size so I want the same neck tension on each loaded round.

I believe Sig makes their own now. I heard ADG made the initial runs of 300 WM brass but I think I read in either rifle shooter or hand loader they manufacture in house now.

That's pretty much what I thought. Thanks. Always trying to learn a little more.
 
Back at you , the 308 is a Great Cartridge !!!

Agreed. In my opinion, it's the best all around hunting option for North America.
You can load 110gn and varmint hunt with it and get high speed, or put up to 200gn in there if you wish. 168 seems to be the magic number for me. I can get close to 2800fps, and get good grouping out to 1000 yards (I dont personally hunt that far, only steel haha)

Low recoil, lots of data, and lots of factory ammo at a reasonable price for those who dont reload.
